Military Microwaves Supplement
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.
Agilent 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).
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.

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.

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.

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.

W. 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.
