The "Powering the Waves" theme was very present at IMS 2014 starting with the kickoff reception party on Monday featuring a water skiing show starring general chair Larry Dunleavy. Larry and his team did an excellent job of running the event and the Tampa Convention center is a nice venue with close proximity to the session rooms and exhibition. Initial numbers show that the conference attendance was 2475, number of exhibit visitors was 1344 and number of exhibitor staff was 3828 for a total attendance of 7647.  These numbers are very similar to the last two years when the event was in Seattle and Montreal so it is very consistent over the last 3 years. The total number of exhibiting companies was reported as 587 with 74 of them being first time exhibitors.

 Reviewing the technical sessions and discussions, we noticed much attention was paid to mmWave technologies, Internet of Things (IoT), tunable filters/antennas, high efficiency amplifiers (envelope tracking, DPD, switched mode PAs, etc.) and biomedical devices/sensors. Showing how popular envelope tracking has become, almost all of the major test and measurement companies had demonstrations in the exhibition showing how to characterize and measure this technique.

The biggest news of the event were significant mergers and collaborations as recently announced mergers of RFMD/TriQuint and Cobham/Aeroflex were made before IMS and right after IMS, ADI announced they are acquiring Hittite.  These announcements are making big waves in the industry with significant consolidation going on. There were also many collaborations evident at the event as AWR/ANSYS are now interoperable with their design software, Agilent and Cascade are partnering to deliver probing test systems and Cooper Mountain systems are integrated into several test systems such as Maury and Focus load pull test sets to name a few.

The MicroApps again offered a wide variety of practical sessions including the Challenges of 5G Technologies that Microwave Journal coordinated.  Looking to the exhibition, we tried to cover as many of the 587 companies as we could and have reviewed almost 100 below.  Below are quick summaries of what each company was displaying at the exhibition by product category.

Software:

AgilentAgilent Technologies announced the latest release of Genesys 2014, its affordable RF simulation and synthesis software. Designed for circuit and system designers, the Agilent EEsof EDA software features breakthrough modulated RF analysis as well as enhancements to its powerful, custom-filter direct synthesis technology. Using Genesys 2014, designers can now simulate digitally modulated RF signals like those found in today’s defense and consumer wireless applications as easily as they do traditional analog RF signals. Unlike other simulators that provide only single-value results for EVM, BER or ACPR, Genesys 2014 delivers breakthrough system budget analysis of these digital modulation metrics for every component in the system block diagram, all in a single pass. This provides RF designers the unprecedented ability to immediately identify culprit components causing digital performance failures.

They also showed EMPro that provides time- and frequency-domain 3D electromagnetic solvers in a full 3D modeling environment tightly integrated with ADS and Genesys. In addition, SystemVue system-level design and verification will show the newest features in high-performance design personalities for wireless/4G, radar/EW and next-generation verification (VTB).

CST

Computer Simulation Technology(CST) announced new features to automate workflows for field source coupling and multiphysics simulation using its System Assembly and Modeling (SAM) framework. Since 2012, the company has offered the ability to link together multiple simulation and post-processing tasks using the SAM framework in its CST STUDIO SUITE EM simulation software. The 2014 release of CST STUDIO SUITE builds on this with features that automate the creation of SAM projects for common design tasks, such as antenna placement, emissions analysis and thermal detuning.

Multiphysics workflows, which combine full-wave EM simulation with thermal simulation, can now be created using the wizard from the schematic view in CST STUDIO SUITE. This means that all the solvers are set up and connected, and the entire simulation started with a single click. For simulations with temperature dependent materials, SAM allows simulations to be iterated until convergence is achieved. Mechanical simulations can be easily added to the workflow, allowing expansion and detuning effects to be calculated. All solvers are integrated in the same parametric 3D modeling GUI, making parameter studies and optimization runs including EM-thermal couplings possible. Field source coupling workflows can also be automated. These allow different components to be simulated with different solver types, with the fields calculated in one simulation used as the excitation in the next. See their video demo here.

EM Software and Systems has released new solvers in FEKO Suite 7.0. A Finite Difference Time Domain (FDTD) solver has been added to its comprehensive set of powerful computational methods as well as the hybridization of the Multilevel Fast Multipole Method (MLFMM) with Physical Optics (PO). Despite the fact that the method is set in the time domain, the use of Fourier techniques allows wideband frequency domain information to be calculated. It can achieve second order accuracy using first order numeric differentiation.

Also, a new hybrid iterative method is supported which allows MLFMM with either PO or LE-PO to be used in the same model. An advantage of this iterative technique is a significant reduction in memory. The MLFMM models the complex part of the structure which contains the fine details. The PO/LE-PO is used to model the smoothly varying part. When using LE-PO together with the MLFMM, bi-directional coupling is included. Applications of the MLFMM-PO (and LE-PO) hybrid span over a wide range of problems including analysis of electrically large antennas, antenna placement studies on large platforms for the purpose of antenna pattern, coupling and radiation hazard analysis.Read our product feature article on this product from the May IMS issue here.

Mician previewed the upcoming new release of µWave Wizard that is scheduled to be available by the end of September/early October. The main improvements include support of optimization/yield analysis/tuning of field strengths and resonant frequencies, together with dual reflector antennas (classical cassegrain/gregorian and displaced axis antennas).

Other features are: improved STEP export (autodetect cylindrical surfaces and curved edges), adaptive sweep of field output variables, display creation time of loaded files in the NTL 3D viewer, the addition of port coordinate systems to 3D field plots and the improvement of the STL import of structures from low precision STL files. New elements will include folded ridged waveguide magic, generic T-junction semicircular to coaxial waveguide, step rectangular/ridged waveguide with longitudinal rounded corners, generic continuous ridged waveguide bend, four-port circular/rectangular junction with screws and ridged waveguide step with radii in the xz-plane.

Microwave Innovation Group (MiG) demonstrated that it had significantly developed its fast hybrid WASP-NET EM CAD and optimization tool. An important feature is the graphic 3D Editor for arbitrary structures, allied to the 3D WNModeler – a powerful 3D editor in addition to the further improved text editor that enables users to combine full 3D generality and flexibility of user-defined structures with WASP-NET’s high calculation speed. Geometry dimensions are parameterized for fast optimizations; lossy materials as well as dielectric and ferrite materials with frequency dependent tensor permittivity/permeability can be included; available 3D CAD data of components of component parts can be imported via standard formats and parameterized to be combined full-wave with desired further elements or additional user-defined 3D structures for fast, direct EM based overall optimization.

NI AWR Corporation announced that they have integrated ANSYS HFSS™ into AWR’s Microwave Office high frequency circuit design software. This integration unites the industry standard for full-wave electromagnetic (EM) field simulation and NI AWR Design Environment™/Microwave Office to quickly and accurately simulate microwave circuits. With this design flow, Microwave Office users can readily access HFSS for analysis of EM fields and coupling of 3D structures like passive components, bumps, bond wires, and pins which are essential to successfully designing and realizing microwave circuits like monolithic microwave integrated circuits (MMICs), densely-populated RF circuit boards and multifunction modules. See their video demo here.

They were showing off new automated workflow options for MRI analysis, new automotive radar whitepaper and a preview of new features in XF7 which include enhanced biological thermal solver, MATLAB report and project optimized gridding.

 

Test and Measurement:

Accel-RF supplies equipment for performing measured long-term reliability assessment on compound semiconductors. To keep up with the shift in GaN from low to high volume, they are expanding their RFBL measurement equipment with the introduction of an 80-Channel RF Bias Burn-In System. The system architecture is derived from the highly developed and field-proven measurement platform product, AARTS. Accel-RF has supplied AARTS equipment to most of the contractors participating in the DARPA wide-band-gap (WBG) semiconductor initiative and the follow-on Title III Program.

Agilent Technologies and Cascade Microtech announced a strategic alliance to provide fully configured and validated RF measurement solutions that streamline wafer-level semiconductor measurements while delivering guaranteed configuration, installation and support. With wafer-level measurement solutions (WMS) from Agilent and Cascade Microtech, semiconductor customers now have the equipment they need to perform accurate and repeatable DC and RF measurements, device characterization and modeling, all while realizing significant time savings to first measurement. Agilent had 19 demos so covering all of their new products would take a whole article but here are some highlights. Agilent announced the availability of a new automatic fixture removal (AFR) option for its PNA Series network analyzers. Previously available only in Agilent’s Physical Layer Test System (PLTS) software, the error-correction technique is the fastest, easiest way to accurately measure non-coaxial devices, saving engineers time and money. They also announced that its FieldFox handheld combination analyzers offer an easier, more cost-effective solution than benchtop instruments, with the accuracy and functionality required for performing precision radar system performance validation, including maintenance and repair in the field.

Agilent announced a series of enhancements for its MXA and EXA X-Series signal analyzers. Agilent’s MXA achieves best-in-class sensitivity through a new Noise Floor Extension (NFE) feature. With this optional capability, the analyzer yields up to a 9-dB sensitivity improvement over MXA models without NFE, without having to compromise the third-order intercept. The MXA and EXA achieve higher frequency stability with a new atomic frequency reference (AFR) option. The option builds on a previous improvement in the analyzers’ short-term frequency stability by offering a 100X improvement in long-term frequency stability. Higher-frequency coverage for the MXA is possible via an external mixing option. The option covers frequencies beyond 26.5 GHz and up to 110 GHz with Agilent M1970 smart mixers, and to 1.1 THz with VDI’s frequency extender. See their video demos here.

Anapico highlighted the 5 MHz to 26 GHz phase noise test system APPH20G – second revision – which provides fast and accurate measurements of SSB phase noise as well as full time domain analysis. The instrument has built-in power detector and frequency counter, operates with either internal or external reference sources and offers measurements from 0.1 Hz up to 50 MHz frequency offset. It can be controlled with LAN (VXI-11), USB, or with GPIB from any PC or laptop. A platform independent intuitive GUI, API library, and powerful SCPI command language set are included. Also shown was the APSIN26TP high output power, low phase noise, fast-switching microwave signal generator covering a frequency range from 100 kHz up to 26 GHz. The instrument provides leading edge output power up to +26 dBm and includes amplitude modulation, frequency chirps, and fast pulse (train) modulation as standard.

AnritsuAnritsu introduced a new family of VNAs targeting the market looking for an economical yet high-performance solution for passive device testing (up to 4 ports). The new Shockline product is a family of rack mountable VNAs based on Anritsu’s non-linear transmission line technology and their “VNA-on-a-chip” architecture. The highly stable system means longer intervals between calibrations, better repeatability up to 125 GHz and excellent temperature stability. The instrument is able to reduce its cost by eliminating the front panel, display, keypad and user interface which are maintained through an external computer and operating system (or instrument drivers such as NI LabView).

AR RF/microwave instrumentation showcased its latest solid-state amplifiers, which included their new 2000S1G2z5 (2000 W Class A CW amplifier) that covers the 1 - 2.5 GHz. Its cost and size is equivalent to a TWTA, but this new amplifier provides better linearity, better harmonic suppression, lower noise level, superior mismatch tolerance, and 100% rated power to any load.  AR also demonstrated their 200 W Class A solid state amplifier which instantaneously covers the 0.7 to 6 GHz frequency range in a single band.  This amplifier is aptly suited for wireless, EMC and military jamming applications.  Their new W Series Class A CW amplifiers covers 80 MHz to 1000 MHz with output powers up to 4000 W.  The AR Modular RF division showed off their new 50 W networking military booster amplifiers called the AR-55 along with their commercial 1000 Watt PEP VHF/UHF base station communications amplifier. 

dBm was featuring their new ultra high bandwidth satellite payload, UAV simulator. With a bandwidth up to 600 MHz, the unit supports link emulation to investigate multipath fading (up to twelve paths) and digital additive White Gaussian Noise impairment to be added to the link. The Satellite Link Emulator with frequency agility provides a cost-effective, time-saving, repeatable total solution for satellite to UAV RF link testing.

Empower RF demonstrated that two is better than one when it comes to featuring high power amplifier systems, introducing their 20-1000 MHz, 1 KWatt compact 5U chassis power amplifier and their new 20-1000 MHz, 500 Watt compact 3U chassis. Excellent engineering and design allows the company to expand its portfolio of compact (size matters) broadband and band specific (below 6 GHz)  high power amplifier systems for jammers, communications, radar/avionics and EMC test and measurement. Both systems on display are rack mount with significant size reductions over competitive offerings

Holzworth released the HSM12001A RF synthesizer module; providing a reliable, agile, broadband (10 MHz to 12 GHz) CW source for our X-band customers.  IMS2014 product previews from Holzworth included the HA7062C phase noise analyzer which now covers a DUT input frequency range from 5 MHz to 20 GHz and measurement offsets of 0.1 Hz to 40 MHz.  The highlight of Holzworth’s IMS product previews was the new HSX Series signal generators, which exhibit industry leading phase noise performance (-144 dBc/Hz at 1 GHz, 10kHz offset) from a broadband signal source and a spurious response of better than -87 dBc. See their video demo here.

NI

National Instruments (NI) featured the NI Power Amplifier Experience where visitors could view different PA exhibits that included envelope tracking and digital predistortion demonstrations on live ET power amplifiers. They also featured an IEEE Hands-on Workshop exploring RF concepts entitled “Efficient RF Design Using Practical Behavioral Models - Bridging the Gap Between Measurements and Simulations" led by Marc Vanden Bossche, Technical Market Development Manager at National Instruments.

In addition, their famous Microwave Jeopardy where they put an IMS twist on the popular television game show was held again in their booth. The game tests the microwave IQ of contestants on topics ranging from wireless standards and measurements to RF in pop culture. NI/AWR and NI/Phase Matrix were also in the booth (see NI/AWR information in the Software section above).  See their video demos here on ET, NI/AWR V11 and Phase Matrix synthesizers.

Noise eXtended Technologies(Noise XT) has introduced the 2 MHz to 7 GHz SLC ultra-low jitter/dual clock synthesizer. The SLC is an affordable single or dual clock USB synthesizer with outstanding jitter in a small package. With a noise floor of -170 dBc/Hz at 10 MHz, the SLC is said to have the lowest phase noise of any synthesizer in a compact, low cost package. The SLC measures just 85 x 110 x 200 mm and is designed to provide clock or local oscillator (LO) substitution signals to semiconductors where jitter and noise really matter. Typically, it will be used to drive data converters (ADC and DAC), direct digital synthesizers (DDS) or high-speed FPGAs and serial links to achieve the highest performance.

Centre stage on the Pico Technology booth was the PicoScope 9300 sampling oscilloscope, which addresses digital and telecommunications applications of 10 Gb/s and higher, microwave applications up to 20 GHz and timing applications with a resolution down to 64 fs. Optional 11.3 Gb/s clock recovery, optical to electrical converter or differential, de-skewable Time Domain Reflectometry sources (40 ps/200 mV or 60 ps/6 V) complete a formidable, small-footprint and cost-effective measurement package. The PicoScope 9300 Series oscilloscopes use triggered sequential sampling to capture high-bandwidth repetitive or clock-derived signals without the expense or jitter of a very high-speed clocked sampling system. The 20 GHz bandwidth allows measurement of 17.5 ps transitions, while the very low sampling jitter enables a time resolution as short as 0.064 ps.

As always Rohde & Schwarz showcased its complete spectrum of test and measurement equipment relevant to the RF and microwave sector. New introductions highlighted included the R&S SGT100A vector signal generator, which covers the frequency range from 80 MHz to 6 GHz. It is equipped with an integrated baseband generator that supports a maximum bandwidth of 160 MHz. and when using the R&S WinIQSIM2 PC software, the generator can quickly and easily deliver test signals for all major digital standards such as LTE, 3GPP and WLAN IEEE 802.11ac.

The company has also expanded the frequency range of its R&S SMW200A high-end vector signal generator to 20 GHz. The R&S SMW200A is claimed to be the only instrument on the market to combine a baseband generator, RF generator and fading simulator in a single box. In addition, it can be equipped with a second 20 GHz path, making it possible to simultaneously generate up to two wideband microwave signals with any type of modulation.

Another expansion sees the R&S SGU100A RF upconverter extend the frequency range of the R&S SGS100A vector signal generator from 12.75 GHz to 20 GHz. By combining the two instruments, users can now generate vector signals continuously from 80 MHz to 20 GHz, e.g. for use in test systems in the aerospace and defense sectors. Once combined, the R&S SGS100A and R&S SGU100A act as a single unit with one I/Q input and one RF output.

Also, the new R&S FPS signal and spectrum analyzer is now available in five models for frequency ranges up to 4, 7, 13, 30 and 40 GHz. It offers measurement applications for all key mobile and wireless standards and can demodulate IEEE 802.11ac Wi-Fi signals thanks to its 160 MHz analysis bandwidth. The higher frequency models are suitable for satellite monitoring applications and for the production of components for the aerospace and defense industry. See their video demos here.

Operating from 9  kHz to 6 GHz with a sweep speed of 24 GHz/sec and resolution BW range of 10 Hz to 10Mhz, the BB60C collects 80 MSamples/second, streams digitized IF data to a computer via USB3.0 at 140 MB/sec, where IF data is converted to I/Q data  format. The new unit has an improved SFDR by 20 dB (typical), flattened noise floor and extended operating temp down to -40 deg C and up to + 65 deg C. Priced at just under $3K.

VDI was featuring their mini VNA extension modules that are a quarter of the volume of previous versions making them ideal for probe stations, operating from 50 GHz to 1.1 THz with exceptional dynamic range and unmatched stability. Partnering with VDI is a new company to watch called Swissto12 that was showing off some impressive new technology in millimeter-wave waveguide. Using a corrugated circular waveguide for much lower loss than can be achieved with rectangular guide, the company was featuring a material characterization it (MCK) that is available for frequency bands from WR-10+ (67-1115 GHz) up to WM250 (750-1100 GHz). They were demoing the characterization kit with a 500 um thick n-doped Si sample. The company was also showing off some very cool looking polymer waveguide (internally gold plated that had been fabricated using 3D printer manufacturing allowing highly customizable waveguide connector solution available in 2 to 3 weeks from order.

Wireless Telecom Group had several interesting demos on display highlighting their Noisecom product lines including the JV9000, which was part of a system to measure the impact of noise and spurs on Vcc of a PLL/VCO circuit and their UFX7000A series which was part of a system demonstrating how broadband noise generated by various sources interferes with the operation of the system as well as testing the impact of broadband jammers on the receiver. In addition, the company demonstrated how the Boonton 4500B and 4542 could be configured as a scalar analyzer to measure transient responses of passive RF components such as power limiters, useful when considering the possible damage to an amplifier due to a power spike on the input.

GoreW. L. Gore & Associates has developed a Cable Installation Simulator to evaluate the stress of installation on microwave airframe assemblies. By comparing signal integrity before and after installation, Gore can engineer assemblies that withstand airframe installation as well as the demands of the aircraft's flight envelope. Prior to installation in the simulator, new cable assemblies are tested to verify the insertion loss and VSWR over a given frequency range. This information serves as the baseline to evaluate any performance change after being routed through the simulator. Then they are stressed by the simulator and re-measured to make sure they will continue to operate to specifications.

 

Materials, Semiconductors and Components:

3D Glass is providing a new photo-definable glass ceramic material has been developed that is processed in a three-step batch process enabling an HVM solution for glass microfabrication. Since the technology is based on a lithographic process, many design and process capabilities not typically associated with glass microfabrication are now possible, such as through glass vias (TGV) for I/Os, complex inductor line structures, high Q-factor architectures, and antenna air bridges on a single electrical substrate. The material’s fine surface finish also enables an MCM capability with fully integrated thin film passive components such as resistors, capacitors and inductors. See their full article here.

American Microwave Corp was showing their CW immune DLVA with 57 dB dynamic range and leading edge detection.  It is a single detector covering -42 to +15 dBm over 2-6 GHz and operating over -54 to 100 deg C. Rise time is 75 ns max and 40 ns typical and log slope of 50 mV/dB nominal.
