Military Microwaves Supplement
Recent Advances in Radar Technology
Using Calibration to Optimize Performance in Crucial Measurements
The delegates, visitors and exhibitors that gathered in Manchester for the 2011 European Microwave Week from Sunday 9 to Friday 14 October have waved farewell to each other but, hopefully, they departed encouraged and inspired to Wave to the Future, which was the slogan for the Week. The slogan epitomises the fact that the event has, at its core, the traditional and established focused conferences, alongside Europe’s premier RF and microwave exhibition, yet is determined to look forward and innovate.
Manchester was at the heart of the industrial revolution in the 19th century and the city was again a positive hub of activity for the Week as the RF and microwave industry took the opportunity to demonstrate its current invention and productivity and illustrate how the development of microwave technology will impact economic recovery and the lives of individuals in coming years.
Even typical inclement, wet October Manchester weather could not dampen the mood as EuMW again showed why it is the leading microwave event in Europe by attracting participants and visitors from around the world, attracted by the comprehensive and complementary mix of academic and commercial content. The Week was organised around three conferences: the 41st European Microwave Conference (EuMC), the 6th European Microwave Integrated Circuits Conference (EuMIC) and the 8th European Radar Conference (EuRAD). View our video coverage of the event including interviews, demos and general conference coverage by visiting our EuMW 2011 Video Library.
More than 1,000 papers were submitted from more than 50 countries and around 375 papers were presented in technical sessions, 200 in posters and 195 in workshops and short courses. On top of that, there were special sessions that included a focussed session on Advances in Nanoelectronics in Radio Frequency Technology and a joint APMC-EuMC session, as well a special half-day Microwaves inside Asia session and the popular Women in Engineering event.
Important recent initiatives continued. In particular, the success of the inaugural EuMW Defence/Security Executive Forum in 2010 saw the EuMW Defence and Security Forum 2011 expanded to a full day, featuring a mix of tutorials, a business Lunch & Learn session, an industrial Panel Discussion and the Executive Forum with contributions from the UK MoD Defence, Science and Technical Laboratory (Dstl) and leading defence/security contractors. For some sessions it was standing room only! View the abstracts, presentations and videos on our the 2011 Defence/Security Forum coverage page.
In its effort to Wave to the Future EuMW recognised the importance of encouraging and nurturing students by continuing established events such as the EuMW2011 Student Challenge and the Tutorial Seminars for Young Engineers, while launching new initiatives such as the Doctoral School in Microwaves aimed at early stage PhD students and the Filter Design Competition, which was open to postgraduate and undergraduate students.
Another significant first was that the Opening Ceremony, which was presented by Professor Konstantin S. Novoselov FRS, from the University of Manchester who received the Nobel Prize for his discovery of Graphene and its extraordinary properties. How long will it be before the fruits of this and similar breakthrough research develops into commercial products that feature in the European Microwave Exhibition? This year the three-day exhibition again proved to be an effective showcase for the design, innovation and application of technology to the commercial market.
However, the exhibition has developed to be much more than just a ‘show floor’. For example, this year, for the first time, the exhibition hall played host to the Microwave Application Seminars (MicroApps) at EuMW 2011, which succeeded in highlighting and elaborating on products and techniques useful to engineers in their day to day design work. The exhibition is a microcosm of the RF and microwave industry with companies large and small, established and embryonic, and from all corners of the globe. There were around 250 exhibiting companies, taking up more than 7,000 m2 (gross), many of whom launched new and significant products. Below is a selection of the new and innovative products on show.
Aeroflex has added to its PXI 3000 Series of RF modular instruments with the launch of the 3036 RF digitizer module, with frequency range extending to 13 GHz, for use in vector signal analysis of complex RF signals. The compact 3036 provides wide instantaneous bandwidth, fast frequency switching, high linearity and low noise, which make it suitable for testing devices and RF components used in high performance wideband RF and microwave communications.
It is a RF digitizer operating over the band 250 kHz to 13 GHz, with up to 90 MHz wide digitized -1 dB bandwidth and 13-bit ADC resolution. It supports high speed frequency switching in less than 325 µs. The 3036 is used with a 3010 Series synthesizer module to provide precision conversion of RF signals into digital IF or I and Q sample data. This combination of modules has a compact size of 4 slots (3 slots for the 3036 and 1 slot for the 3010) to minimize overall test solution footprint. The extended frequency range up to 13 GHz enables the measurement of harmonic characteristics of fundamental signals below 6.5 GHz.
The focus for Agilent Technologies was on providing solutions for ‘solving tomorrow’s test challenges’. To this end the company expanded its PNA-X Nonlinear Vector Network Analyzer to 67 GHz, along with a new 67 GHz phase-reference calibration standard, configured to work with the 67 GHz PNA-X NVNA. Using this hardware, designers can characterize and model components accurately up to frequencies of 67 GHz. In addition, X-parameters can be measured up to 67 GHz, providing an accurate model of linear and nonlinear component behavior at very high frequencies and wide bandwidth.
The new 67 GHz NVNA enables engineers to make high-frequency nonlinear measurements across a very wide frequency bandwidth. The 67GHz phase-reference calibration standard enables accurate and traceable nonlinear measurements to 67 GHz using the NVNA. The phase reference generates a comb of frequencies from 10 MHz to 67 GHz with a known cross-frequency phase relationship traceable to the National Institute of Standards and Technology. This relationship calibrates the NVNA to measure spectrum to 67 GHz with a predictable and accurate cross-frequency phase.
To address the analysis and generation of wide bandwidth signals the company showcased the industry’s first 160 MHz analysis bandwidth option for the high-performance PXA signal analyzer. Wider bandwidth signal analysis, up to 160 MHz, is necessary to cover all of the bandwidths supported by 802.11ac. The PXA signal analyzer with 160 MHz bandwidth addresses this need, as well as any other application that requires engineers to analyze wider bandwidth signals. Its advanced performance provides valuable insight that helps speed the design, verification and troubleshooting of current and future 802.11ac devices. Moreover, when combined with the 89600 VSA software’s 802.11ac modulation analysis, the PXA enables high-performance, comprehensive analysis of 802.11ac signals.
Not all new announcements can be covered here but another of note is the first complete and compliant test solution for 60 GHz wireless devices, including WiGig, WirelessHD and IEEE 802.11ad devices. Using the company’s new M8199A Wideband Waveform Center software and the M8190A arbitrary waveform generator or a high-performance Infiniium 90000 X-Series oscilloscope, design teams can verify the overall performance of new 60 GHz wireless devices and validation engineers can perform specific measurements with expected values for transmitters and receivers as defined in the standard.
For Anritsu Corporation the theme was the company’s wide range of innovations that have enabled significant advances in test equipment through new technology and measurement methods. Designed for R&D and manufacturing environments, the VectorStar VNA features a broad frequency range of 70 kHz to 70 GHz, fast measurement speed, superior dynamic range and advanced time domain processing with up to 100,000 data points. It also offers users expandability, including frequency range upgrades to 110 GHz and higher, two-port to multiport upgrades, and linear to nonlinear measurement upgrades, meeting long-term measurement requirements.
Also on display were the MS2830A Signal Analyzers, which support high-level measurement speeds and high RF performance at low cost to help raise R&D efficiency and productivity. The MS2830A analyzer has swept spectrum analysis, FFT signal analysis, and a precision digitizer function as standard. The MS2830A offers a standard analysis bandwidth of 31.25 MHz. This best-in-class level accuracy of ±0.5 dB across a 6 GHz span uses innovative leveling and compensation techniques.
For field applications, the company showcased the MS2035B/MS2038C handheld VNA Master™, S332E SiteMaster™ broadband cable and antenna analyzer and Spectrum Master™ models, including the MS2726C – claimed to be the only handheld spectrum analyzer with frequency coverage up to 43 GHz. The lightweight, easy-to-operate, durable analyzers are suitable for engineers and technicians responsible for the deployment, installation, and maintenance of wireless networks.
Ken Foan of ETS-Lindgren (EMEA Sales & Marketing Director). The company has putting a lot of focus antenna test, co-operating with Agilent Technologies and the NSI. This includes over-the-air testing, mil-standard testing (in Turkey, UK and Sweden) and MIMO studies.
ETS-Lindgren is well-known for the design and manufacture of high quality anechoic absorber material for electromagnetic (EMC), radio frequency (RF), microwave and wireless test chambers and ranges. Expanding on this expertise, ETS-Lindgren launched its new FlexSorb absorber coating product at the annual symposium of the Antenna Measurement Techniques Association (AMTA). FlexSorb offers the same high performance characteristics as the company’s traditional absorber, yet it can bend significantly, without breaking. FlexSorb’s durable absorber tips actually resist breakage, which is especially important for high traffic areas, chamber entry ways and when using on a chamber floor. In addition, the new coated absorber is dust resistant, easier to handle, non-hygroscopic and flexible! We had the chance to play with the sample and I have to admit, it feels pretty cool.
The company was also showing off on their N255x filters. These high performance e power filters are fully tested for attenuation performance, voltage withstanding to 1 kV for thirty seconds, and insulation resistance. The N255x filters provide 100 dB insertion loss from 10 kHz to 10 GHz in both symmetric and asymmetric modes up to full load, offering maximum protection in TEMPEST and EMP applications, along with fully accessible end chambers for termination of input and output cabling.
Mesuro demonstrated both fundamental load pull, to 67 GHz, and active harmonic load pull using the Rohde &Schwarz ZVA67 VNA as the basis for the system. In this configuration customers can benefit from waveform engineering whilst utilizing existing RF & microwave hardware. Using a Focus Microwaves MPT harmonic passive tuner, the company also demonstrated how the use of an impedance transformation can impact the active portion of the load pull solution. With this configuration it is possible to provide all the benefits of the open loop active harmonic load pull solution, including the ability to achieve Gamma Load >=1.
LeCroy was showing off their WaveRunner 6 Zi Series that operates from 400 MHz to 4 GHz with 8 bit and 12 bit resolution. The WaveRunner 6 Zi has 40 Gs/s sampling rate and 256 Mpts of analysis memory. It also has a 12.1” widescreen WXGA color touch screen that rotates from landscape to portrait. We don’t always see LeCroy at microwave shows but they had a nice large stand at EuMW.
IVCAD advanced measurement and modeling software, offered by Maury Microwave and AMCAD Engineering supports multiple load pull techniques including traditional load pull using external instrumentation, VNA-based load pull, active load pull and hybrid load pull.

The Maury Microwave MT2000-series mixed-signal active load pull system, powered by Anteverta Microwave, is available in 6, 18 and 26 GHz versions. As an active load pull system, the MT2000 is extremely fast, with measurement speeds of up to 1000 points per minute in CW and pulsed environments. When operating in a modulated signal environment, the system has the capability to control up to 120 MHz of instantaneous wideband impedances.
NMDG released the NM310S, a cost-efficient nonlinear starter kit, allowing engineers to make their first steps in the nonlinear world with their vector network analyzer. The starter kit is a software/hardware combination, enabling the VNA to characterize in time and frequency domain the harmonic behavior of active components from 20 MHz to 3 GHz. It supports a selection of four-port Agilent and Rohde & Schwarz vector network analyzers given the proper options.
Once acquainted, engineers will be able to extend, with incremental investment, the capability of their system to support the design and test efforts of their company or institute. They will then be able to perform nonlinear measurements under non-50 Ω conditions by using passive and/or active tuners.
National Instruments signaled their new emphasis on the RF and wireless markets last August during their NI Week conference in Austin and at MTT-S IMS in Baltimore. The recent acquisition of AWR and Phase Matrix last May has also helped extend the frequency range of their products well into the microwave spectrum. Company representative Jin Bains (Product Marketing) participated in the MWJ organized Defence And Security forum on Radar and company founder Dr. T flew out to attend his first European Microwave Week. Dr. T was very busy scoping out the other vendors on the exhibition floor, especially interested in learning more about GaN technology. Here’s a CEO who genuinely enjoys technology and its possibilities.
In the NI booth, the application engineers and product managers were busy highlighting a number of products including a complete PXI-based solution for RF power amplifier (PA) validation and production test. The NI PXI solution for power amplifier test integrates a variety of mixed-signal, high-performance instruments to meet the demanding requirements for fast and precise PA test in validation and production environments. The demonstration features the latest NI PXI instruments including the NI PXIe-5665 14 GHz vector signal analyzer, the NI PXIe-6556 digital per pin parametric measurement unit (PPMU), the NI PXIe-4154 battery simulator and the NI PXIe-5186 12.5 GS/s, 5 GHz digitizer. With these PXI-based modular instruments, engineers can perform a wide variety of PA tests and measurements such as power versus time (PVT), error vector magnitude (EVM), adjacent channel leakage ratio (ACLR), current leakage, harmonics and open-shorts tests.

These compact adaptors combine good mechanical and electrical properties, with excellent performance in industrial applications and ease of use. A particular advantage is the facility for verification directly after calibration.
A significant introduction for Rohde & Schwarz is the new, high-end R&S FSW signal and spectrum analyzer. The R&S FSW comes in three models that cover the frequency ranges 2 Hz to 8 GHz, 13 GHz or 26.5 GHz and has been specifically designed to meet the requirements of development laboratories in the aerospace, defense and communications industries. The practical 12.1" touchscreen offers a MultiView function display of the results of different applications at the same time, enabling users to keep track of even the most complex signal analyses and find errors easily. An additional benefit is the elimination of time-consuming switching between measurement applications.
At 10 kHz carrier offset, the instrument achieves a phase noise specification of less than –137 dBc (1 Hz). Equipped with the R&S FSW-K6 option, the R&S FSW also supports comprehensive analysis of pulsed signals, e.g. for radar applications. Its broad analysis bandwidth of up to 160 MHz enables it to measure wideband, hopping and chirp signals, which makes it ready today for the requirements of tomorrow's wireless standards such as 802.11ac.
The company has also enhanced its analog R&S SMB100A mid-range signal generator by adding new frequency options. The R&S SMB-B120/B120L and R&S SMB-B140/B140L options (L versions without step attenuator) enable the generator to cover the frequency range from 100 kHz to 20 GHz and 40 GHz, respectively. The instrument can now handle everything from analog RF to microwave applications. Also featured at EuMW was the new 600 MHz R&S®RTO oscilloscope that is available as a two-channel or four-channel model, offering a high-performance oscilloscope in the lower bandwidth range. With regard to specifications and features, the new 600 MHz R&S®RTO models (R&S®RTO1002 and R&S®RTO1004) are identical to the previous 1 GHz and 2 GHz models.
A critical step in testing any 802.11 device is to generate standard-compliant 802.11ac test signals. Agilent’s Signal Studio for WLAN software aids this task by enabling the creation of 802.11ac waveforms with BCC or LDPC channel coding, all MCS codes, and single or multi-user MIMO up to four streams. Generation of up to 80MHz bandwidth signals are supported with the company’s ESG, MXG or PSG vector signal generators and the PXB baseband generator and channel emulator; 160 MHz bandwidth signal generation is possible with support from two Agilent vector signal generators.
Ansys was featuring many of the company's 3D EM (HFSS) and circuit design (Designer) products but we were intrigued with the Microwave Education Kit developed by Elliptika which offers practical course examples based on components' behavior. There is a kit for both active and passive devices. This education kit, EDUCTIKA, is composed of basic sub-sets of microwave passive components aimed at teaching students the fundamentals of microwaves. It allows students to develop skills in various subjects through practice with real devices. It covers subjects such as the physics of microstrip lines, impedance matching devices, CAD tools using Eductika component library available in Ansys Designer, etc. We hear everywhere that there is a shortage of engineers in our field and these types of interactive tools for students can certainly be a first step to generating more interest in our field.
As sponsor of the MicroApps session at European Microwave Week, AWR was very busy organizing speakers and presenting their own talks on a variety of RF/MW design issues. AWR’s Chris Paris provided the keynote on Wednesday and lined up famed PA guru Steve Cripps to provide the keynote on Tuesday.
In addition to the in-booth software demos, the company was also featuring a number of free workshops with partners (NI, Rhode & Schwarz, and Anritsu) as well as conducting private and personalized demonstration of AWR software to its valued customers. AWR and National Instruments (NI) were also jointly demonstrating “hardware-in-the-loop” in the AWR stand by showing AWR software connected to NI LabVIEW. Infineon high-power PA is studied using Visual System Simulator in conjunction with PXI RF signal generator and analyzer.
Editor David Vye had the chance to speak with Executive VP, Ted Miracco. Ted was excited to talk about the company’s latest partnership with Antenna Magus. Antenna Magus provides a database of many different highly-characterized antenna types that can be exported to AWR's EDA tools for EM analysis, integration, tuning, and optimization. The first result of this relationship is AWR Connected™ for Antenna Magus, an interface between the respective firms' software products that expedites antenna design from synthesis with Antenna Magus to full circuit/EM simulation with AWR's Microwave Office™ and AXIEM® software tools. This allows Microwave Office and AXIEM software users to integrate antennas into their designs, targeting commercial and military terrestrial and satellite wireless communications systems.
AWR’s Microwave Office software is also resident in the Anritsu VectorStar VNA. Having high frequency design tools resident on a Vector Network Analyzer (VNA) provides a streamlined work flow that reduces the time required to transfer measured data to a simulator running on a separate PC or workstation. To complement this demo, a new application note is also available. Entitled “High-Speed Serial Backplane – SERDES Design Example” it demonstrates these advantages in the design of a high-speed serial backplane, such as allowing good channel design to be achieved at early development stages and validating the design as it grows in complexity throughout the design process.
Computer Simulation Technology (CST) previewed its CST MICROWAVE STUDIO version 2012, which features a new multi-layer solver. This is a 3D planar electromagnetic solver for planar modeling and analysis. It is based on the Method of Moments (MoM) and enables users to simulate multi-layer geometries accurately and efficiently. The new solver features automatic layer stack generation from 3D models, open boundaries, automatic edge mesh refinement as well as automatic de-embedding of ports.
Typical applications are RF designs such as planar antennas and filters, as well as MMIC and planar feeding network designs. Accurate co-simulation of complex micro-strips and transmission lines in 2D is facilitated in CST STUDIO SUITE by CST DESIGN STUDIO. The new multi-layer solver makes this easier than ever, and together with CST's new System Assembly and Modeling (SAM), the new solver can be used to simulate planar components of complex systems even more efficiently.
Today’s design engineers have to deal with increasingly complex systems whose performance might be affected by the interdependence of components. SAM provides an environment that simplifies the management of simulation projects and helps engineers to compare the results of different solvers or model configurations within one simulation project. A linked sequence of solver runs can also be initiated. All simulations and links can be defined easily in SAM to enable for example a seamless multiphysics work flow. In addition, SAM can be used to set-up 3D systems built from various components.
Mesuro launched a vector network analyzer based software solution for Fundamental Only Active Load Pull. The Fundamental Only software implementation follows the format, structure and operation of the existing main system software. This allows a customer to both reutilize existing equipment and also expand to full harmonic load pull at a later date through additions of software and hardware modules. The current implementation currently supports the Rohde & Schwarz ZVA family of Vector Network Analyzers and the Agilent PNA-X family.

Mitsubishi Electric introduced an internally matched GaN HEMT power amplifier for C-band satellite communication, which offers a power-added efficiency of 67 percent. This figure is achieved by placing individual tuning circuits in front of each GaN HEMT cell on the substrate. This means that every GaN HEMT is controlled via an optimized harmonic tuning circuit consisting of a MIM capacitor and a spiral indictor. In addition, the PAE is improved by the GaN HEMT’s second harmonic impedance providing a highly accurate input control. Measuring 17.4 by 24 by 4.3 mm and with a mass of 7.1 g the device delivers a high output power of more than 100 W or, respectively, 50 dBm. The new GaN HEMT will allow for the design of smaller and lighter transmitter devices helping microwave communication satellites to save power.

Each LoopBack relay combines two DPDT electromechanical relays in one package that includes an internal bypass path for Automated Test Equipment (ATE) applications. The LoopBack relay combines the technology of two Teledyne RF300 Series relays which eliminates the need for external PCB traces in loop-back test applications. The LoopBack relay is designed for digital signaling applications and provides excellent signal integrity up to 12 Gbps data rates. Also released was the RF332 that is designed to exhibit high repeatability and is capable of transmitting signal integrity up to 12 Gbps data rates as well as RF performance over a bandwidth from DC-8 GHz. The sensitive RF332 relay has a high resistance coil, thus requiring extremely low operating power.
The XMN and XMNP low-noise signal sources from Pascall are designed to provide a range of high-performance building blocks for frequency synthesizer designers and can also be used as stand-alone fixed-frequency signal sources. The XMN combines a Pascall OCXOF with a frequency multiplier and bandpass filter, to give an output with ≤-80dBc sub-harmonics and exceptionally low noise floor. In addition to the multiplied frequency, an output is provided at the oscillator's frequency. The XMNP adds a phase-locked loop, to enable the module to be locked to an external reference.
Because of their very low phase noise floor, the XMN/XMNP series offer an alternative to SAW oscillators in many applications, giving an improvement in close-in phase noise. A further advantage is the availability of crystals at custom frequencies, which eliminates the high development cost and lead time associated with non-standard SAW frequencies. Typical applications include low-noise frequency synthesizers, phase noise test systems, radar and EW, NMR/MRI and scientific research.
Q-par Angus Ltd launched a new ‘base-line’ compact ultra-wideband 0.5 to 18 GHz spiral antenna intended for UWB communications, feeds, radio surveillance and direction finding applications.
