IMS2019 Was a Hub of Activity
Event Summary and Wrap Up
IMS2019 returned to Boston in its normal 10 year rotation through major centers of microwave activity. The theme was the Hub of Microwaves as Boston is laid out in a spoke and hub highway formation around the city to access the suburbs where many microwave companies reside. The event took place from June 2 to 7 at the Boston Convention and Exhibition Center (BCEC) and featured the Radio Frequency Integrated Circuit (RFIC) Symposium, the International Microwave Symposium (IMS), the 5G Summit and the ARFTG Microwave Measurements Conference. The social and networking events took place throughout the revitalized Seaport District in Boston. This neighborhood, adjacent to the BCEC, has undergone a remarkable transformation since the 2009 IMS, and is now home to many museums, shops, restaurants and nightlife. The 2019 International Microwave Week will be memorable for years to come.
Boston has a rich microwave heritage that continues through today. The Radiation Laboratory, run by the Massachusetts Institute of Technology (MIT) during the 1940s, made seminal contributions to the emerging microwave engineering field. Much of this knowledge was transferred to surrounding industry and universities in the 1950s. The local IMS Steering Committees took particular pride in balancing the traditions of IMS with innovative twists and a focus on creating the best experience for the technical and industry exhibition attendees.
Putting a name with a face, we had the opportunity to talk with Jay Diepenbrock, SiRF Technology Consultant, who was at IMS representing IEEE’s MOVE truck. Tucked in the far right corner of the show floor, but has had a phenomenal impact in rescue operations was IEEE’s MOVE truck. MOVE (MObile VEhicle ) is an IEEE Project that creates and operates a vehicle for disaster relief providing needed communications, light and power to victims. This Mobile Outreach Vehicle operates with a group of IEEE member volunteers to provide disaster relief. The volunteers bring a wide range of experience and use their unique skills along with demonstrating their technologies that are used in the industry to help people during disaster relief. Jay Diepenbrock provided the tour and was passionate about the cause explaining how the vehicle has actively been involved in responding to disaster survivors who have survived the initial catastrophe. "Unlike other First Responder Efforts (e.g., ARRL, RACES), this project is intended to help the disaster survivors by supplying valuable services until normal infrastructure is restored," said Jay Diepenbrock. Additionally it energizes the IEEE volunteer base, highlights skills, promotes public awareness and more.

Copper Mountain showed a CobaltFx system with a C4409 VNA (4-port, 100 kHz to 9 GHz) and FET1854 Frequency Extension Modules (18 to 54 GHz) on ports 1 & 2 to demonstrate vector mixer measurements and FEV-15 Frequency Extension Modules (50 to 75 GHz) on ports 3 & 4 to demonstrate filter measurements. The vector mixer measurement setup had a reference mixer to allow transmission phase measurements and a low pass filter to reject the unnecessary image signals. Additionally, the LO was supplied from an external source to the LO port of the two mixers via a splitter. Two calibrations were performed for this setup: first, a full 2-port calibration at the ports of the two extension modules, and then a second-tier calibration using open, short and load standards to de-embed the reference mixer setup. Finally, the measurements shown were conversion loss, group delay and return loss measurements of the mixer under test. The second setup on ports 3 & 4 of the CobaltFx system shows a band pass filter measurement. By switching to FEV-15 under the ‘Frequency Extender’ menu option on the VNA software, we were able to quickly take measurements in the FEV-15 band without reconfiguring the physical setup. For calibration, a full 2-port calibration was performed using the FEV-15 waveguide calibration kit to achieve highest accuracy. The final measurements shown were return loss and insertion loss of a WR-15 filter. Complex measurements such as vector mixer measurements can be performed just like a base VNA. The setup also demonstrated the use of one 4-port VNA to drive two different sets of frequency extension modules.

VIDA Products was demonstrating its high performance, low power, surface-mount, small size and low phase noise YIG oscillators and filters. VIDA integrates proprietary YIG resonators with RFICs to achieve YIG performance with lower power dissipation, smaller size and the convenience of surface-mount packaging. VIDA’s oscillators and filters support both commercial and defense systems operating at frequencies of 5 GHz and higher.
Wenzel Associates instruments combine industry leading Ultra-Low phase noise performance with standard 19” rack mount configurations (1U, 2U, 3U and 5U). A variety of standard rack source solutions are available with pre-configured output frequencies, but custom solutions are also available up to 8U. These units deliver superior performance at a lower cost than a variable low noise frequency synthesizer with the flexibility of providing only the fixed frequencies needed for requirement. Frequency outputs up to 26 GHz are available with Ultra-Low or Golden phase noise performance options are available. Multiple frequencies and multiple outputs are provided as needed as well as phase locking with an external reference. Each instrument includes a low noise power supply and/or low noise voltage regulators to help minimize power supply line related spurs, and provides clean power to drive the internal oscillators and modules.
They were also featuring 10 and 100 MHz low noise PCB mount crystal oscillators with noise levels down to -178 dBc/Hz at 100 kHz offset. They certainly make some of the best oscillators in the industry and used as a reference signal in many high performance applications.
WIN Semiconductors, the largest compound semiconductor foundry, made two announcements at IMS, strengthening the company’s position supporting mmWave systems. Not to be overshadowed by silicon and GaN, WIN announced the commercial release of its highly integrated E-PHEMT process, PIH1-10. The PIH1-10 platform combines a 100 GHz ft E-PHEMT with monolithic PIN and Schottky diodes, which support all the circuit functions in a mmWave front-end for 5G handsets, base stations and radios for backhaul and fronthaul. The single supply E-PHEMT achieves transmit power levels of 30 dBm and receive noise figure of 2.5 dB, and the integrated PIN diode has less than 1 dB insertion loss.
WIN also announced the commercial release of a 0.15 μm GaN on SiC process, the NP15-00, for mmWave PAs operating to 35 GHz. The GaN device, which is designed to operate at 20 V, uses a source-coupled field plate to improve breakdown voltage. The process, which runs on 100 mm wafers, enables through-wafer vias for low inductance grounding. At 29 GHz, the GaN device achieves 3 W/mm saturated output power with greater than 50 percent efficiency — without harmonic tuning — and 13 dB linear gain.
The Wireless Telecom Group featured product demonstrations from their Boonton, Noisecom and CommAgility segments, highlighting how each addresses customer needs. With communication systems using complex modulation, single tone gain and output power measurements and two-tone linearity measurements are no longer sufficient to measure component and system performance. Buying vector signal generators and signal analyzers to replicate and measure actual OFDM signals can be expensive. Alternatively, using a Noisecom broadband noise source at the input, to simulate the modulated signal, and a Boonton peak power meter at the output is an elegant and comparatively inexpensive method for measuring and assuring system performance. The technique measures crest factor, which is more sensitive to the initial compression which quickly degrades system linearity and data throughput. To add insight, the crest factor measurement can include the complementary cumulative distribution function (CCDF), a probabilistic assessment of system performance.
W. L. Gore & Associates (Gore) played a key role in the Apollo 11 mission and featured their Apollo story and artifacts at IMS 2019 in addition to products for 5G and aerospace & defense testing. Gore’s contributions to space exploration began very early in its history. In just ten years, the company went from a Delaware basement where the company was founded in 1958, to the moon with multiple products contributing to the success of the July 1969 Apollo 11 moon landing. Gore wire and cable supported getting men to the moon, was involved in the seismographic experiments on the moon, and helped the astronauts to navigate back home.
Wolfspeed demonstrated two GaN on SiC power transistors in the company’s booth at IMS: a 35 W, X-Band, 50 Ω matched PA for radar applications and a 60 W average (400 W peak) device targeting the 3.6 to 3.8 GHz 5G band in Korea. Although Wolfspeed sees GaN as the RF growth engine, it maintains the LDMOS portfolio acquired with Infineon’s RF power business. Wolfspeed’s marketing strategy is to let the market requirements and customer choose the “best” technology fit for the application. Simon Wood, the senior director of RF product development and applications, said the lower frequency, single cellular band applications favor LDMOS, while the multi-band and higher frequency PAs favor GaN, where GaN’s cost is offset by eliminating several single-band PAs or through operator OPEX savings.
Xilinx discussed applications for the Zynq® UltraScale+ RFSoC, from 5G infrastructure to defense systems. The RFSoC platform builds on Xilinx’s leadership in FPGAs, adding direct sampling 5 GSPS, 14-bit ADCs and 10 GPSP, 14-bit DACs. Now in its third-generation, the UltraScale+ RFSoC covers the full sub-6 GHz spectrum, and mmWave spectrum can be block down-converted to use the performance of the RFSoC. For massive MIMO radios, Xilinx estimates the UltraScale+ architecture will consume 50 percent less power and occupy 75 percent less board area. The capability and flexibility of the platform makes it applicable for cable PHY and phased array radar.
