Microwave Journal reached out to some leading microwave companies and gathered the following exclusive product previews for IMS2016.
Analog Devices (ADI) (Booth 1519) will showcase a number of new products that focus on improving efficiencies in power, design time and cost to meet increasingly rigorous demands across applications in the communications, industrial, and aerospace and defense industries. ADI will feature a PLL synthesizer with integrated VCO that allows mobile network operators to improve cellular base station performance and the quality of wireless service. The new ADF4355 PLL with VCO synthesizer operates up to 6.8 GHz, a frequency band that allows significant margin to industry’s current carrier frequencies. Another product is a 10 W GaN amplifier that operates between 0.01 and 1.1 GHz with ±0.5 dB gain flatness. The HMC1099 GaN amplifier is ideal for Industrial applications where GaN technology is needed to meet the increasing demands on battery lifetime, energy and low cost requirements while reducing the system complexity in a smaller footprint.
The HMC8100 and HMC8200 product family of intermediate frequency receiver and transmitter chips will also be featured, which offers a highly integrated compact solution for microwave radio as well as broad market RF communication applications. The T/R functionality across the broad frequency range combines the value from what were traditionally four to five separate chips into a single IC.
Finally, a 100 W high power microwave amplifier that covers 2 to 18 GHz will be on display. High power and small form factor are achieved using proprietary power combining GaN MMICs. Small and rugged, the solid-state high power amplifier is well suited for EW applications and the replacement of TWT amplifiers – offering long lifetime reliability, continuous 2 to 18 GHz bandwidth, and no need for a high voltage power supply.
The Ampleon (Booth 2149) name may not have appeared at IMS before but the company’s expertise and technology will be familiar as this spin off from NXP Semiconductors attends the show as a uniquely focused RF power technology company for the first time. As well as highlighting its latest developments in its key traditional markets such as wireless infrastructure, broadcast and industrial, scientific and medical, the company will demonstrate the strategic growth of the A&D segment. The company’s focus on the RF Energy markets will continue, enhanced by the participation of the RF Energy Alliance at the Ampleon Booth 2149.
Anritsu Co. (Booth 949) will display the ability to make vector network analyzer (VNA) measurements of devices under test (DUT) stimulated with wideband modulated signals. Utilizing the high speed IF digitizer option in the VectorStar® VNA series (see Figure 2), measurements can be made with up to 200 MHz of instantaneous bandwidth in the receiver. The primary enabler of wideband VNA measurements is the Anritsu Non Linear Transmission Line (NLTL) sampler that can capture wideband modulated signals for waveform analysis. The result is the ability to perform VNA corrected modulated measurements with bandwidths up to 200 MHz and carrier frequencies up to 70 GHz with 14-bit dynamic range resolution.
Also on display will be the MS46524B 4-port Performance VNA in the Anritsu ShockLine™ VNAs. The MS46524B will be equipped with the E-Band option that makes E-Band component design and manufacturing more affordable. These VNAs are also based on the Anritsu NLTL technology, which in this case enables high performance millimeter wave measurements at a lower cost than alternative technologies. In addition, the option provides a dedicated solution focused on the enhanced E-Band, allowing further cost reduction by stripping out components for unused bands.
ANSYS (Booth 1539) will feature new technology to analyze installed antenna performance. ANSYS Savant is now a part of the ANSYS HFSS design environment. Savant’s industry leading Shooting and Bouncing Ray plus (SBR+) technology provides fast and accurate prediction of installed antenna patterns, near fields and antenna-to-antenna coupling on electrically large platforms (see Figure 3). Savant is ideal for analyzing antennas installed on platforms and in environments that are 10s to 1000s of wavelengths in size, can compute accurate solutions with incredible speed.
ANSYS will also feature EMIT, software for predicting radio frequency interference (RFI). EMIT works hand-in-hand with ANSYS HFSS to combine RF system interference analysis with best-in-class electromagnetic simulation for modeling installed antenna-to-antenna coupling (see Figure 4). The result is a complete solution that reliably predicts the effects of RFI in multi-antenna environments with multiple transmitters and receivers. EMIT’s powerful analysis engine computes all-important RF interactions including nonlinear system component effects. EMIT solves radio frequency interference in environments ranging from large platform cosite interference to receiver desense in electronic devices.
AR (Booth 1711) has some impressive high power products that it just released (we are talking about really high powers here) — a Class A RF amplifier capable of delivering over 50,000 W with excellent harmonic performance of -40 dBc minimum. Another recent milestone is a 10,000 W linear amplifier covering the entire 80 to 1000 MHz frequency band as well as a 1 to 2.5 GHz amplifier capable of producing over 3,000 W. These products are leading the industry in energy efficiency and are capable of delivering extremely large field strengths when combined with a matched antenna. At IMS they are introducing a new series of solid- state pulse amplifier products that cover 1 to 4 GHz in various bands. These amplifiers have excellent harmonic distortion, ease of maintenance, very high MTBF and produce output powers approaching 20,000 W. Typical applications include EMC and radar testing.
AR is also showcasing their ultra-wideband single amplifier 0.7 to 6 GHz (see Figure 5), hybrid power modules and benchtop amplifiers in both Class A and Class AB designs. These single band amplifier designs incorporate the latest GaN devices, and utilize chip and wire technology, proprietary combining techniques, and are manufactured in its recently expanded microelectronics hybrid facility. Typical applications include semiconductor testing, wireless communications, EMC, IED and EW.
CST (Booth 739) will release CST STUDIO SUITE 2016 at IMS, the latest version of the company’s EM simulation software. One area that has seen particular development is antenna design and placement —this has always been a crucial and fast-moving field, but with the rise of wearable electronics, V2V and the IoT, more engineers are finding that understanding the installed performance of antennas are crucial to the success of the device. In addition, technologies such as mmWave and smart antennas mean that antenna arrays now are used in numerous applications. The integration of Characteristic Mode Analysis (CMA) allows patch antenna designers to visually analyze how the geometry of the antenna and the flow of current correspond to its resonances (see Figure 6). This is particularly useful for analyzing and optimizing integrated printed antennas, which often have to be compact and multiband to fit in a portable device.
Also, a range of new features including real ground, GPU acceleration for the ray-tracing asymptotic solver and improved workflow for hybrid antenna-platform simulations help engineers investigate the installed performance of antennas faster and more flexibly. New features in the CST array design tool also make it easier to develop antennas from creating the initial element to analyzing the installed performance of the whole device.
The Dover Microwave Products Group (Booth 1639) has developed a series of K&L Microwave® brand high power, lowpass filters for these types of requirements. Multiple design innovations reduce insertion loss, minimizing dissipated power to provide higher power handling in a relatively small package. Cutting off at frequencies as low as 460 kHz and handling up to 3.0 kW CW, the filters are remarkably compact. Two part numbers delineate the current cut-off frequency range for this series. Part number 3LL10-0.46/XQ0.70-N/N, with 0.5 dB of insertion loss from DC to 460 kHz and 60 dB rejection at 700 kHz, was designed to handle 2.5 kW in the passband and passed qualification with 3 kW input power. Dimensions are 12.3"L × 3.5"W × 2.1"H. Part number 7LL10-100.0/XQ140-N/N features 0.5 dB insertion loss from DC to 100 MHz and 60 dB rejection at 140 MHz, handling 1.1 kW CW power. Size is 4.51"L × 1.9"W × 1.25"H. Both are quite small given frequency and power (see Figure 7).
The Microwave Products Group will also launch a new K&L Microwave brand Thin Film Lumped Element (TFLE) product line utilizing sputtering deposition on alumina. Inductors are realized as high impedance lines, with capacitors implemented as low impedance sections or interdigitated structures. In direct coupled schemes, this approach supports fractional bandwidth beyond 60 percent of center frequency, exceeding the range of relatively narrow bandwidths typically realized with quarter-wavelength edge-coupled lines. In addition, the ability to alter the nature of the main coupled sections and to mix inductors and capacitors allows the reduction of rejection skirt skewing effects associated with wide bandwidths. Sonnet® software and co-calibrated port capabilities facilitate optimization of performance and size during the design process.
Focus Microwaves (Booth 1349) will feature their RAPID digital tuner that is the heart of a precision, high-speed, load-pull device characterization system. The RAPID has been developed by Focus’ UK subsidiary MESURO and is suitable for every phase of the design and production test cycle. This series of new digital tuner products provide performance, reliability and cutting edge features for a reasonable cost. The RAPID series is compatible with the hardware and software of existing labs, thereby allowing users to easily upgrade their existing systems.
The RAPID can be used as a stand-alone impedance synthesis and measurement system, or combined into a hybrid solution when paired with Focus’ MPT series harmonic tuners. The passive tuners can be used to synthesize fixed harmonic impedances in a high speed fundamental active setup. With this modular configuration the user benefits from speed, increased tuning range for F0, CW, pulsed and modulated signals while reducing cost and simplifying the system (see Figure 8). The system provides full wave characterization (a1, b1, a2, b2) and DC in 20 ms per measured point. A full application programming interface (API), compatible with a large variety of commonly used compilers is available for impedance control and measurement automation. This programming library allows the user to synthesize any impedance, perform measurements from a variety of platforms.
