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.

MOVE Truck

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. For more information and detailing regarding the truck, visit

The IMS2019 Exhibition consisted of over 600 exhibiting companies who represent the state-of-the-art when it comes to materials, devices, components and subsystems, as well as design and simulation software and test & measurement equipment. It is the best place to find out about new products and services being offered in the RF/microwave industry. It is also the best place to network with industry experts to find out answers to your design, simulation and test & measurement challenges.

The Exhibition also included the MicroApps and Exhibitor Workshops addressing new products, processes and applications of interest to the microwave community. There was more than 65 15-minute presentations given by representatives of companies from around the world as part of the MicroApps program. The Industry Workshops were two-hours each in duration, with one or more presentations. They are awarded to a single company or group of companies to discuss a specific technical topic in much greater depth than the MicroApps seminars, possibly with live demonstrations and attendee participation. Here is a summary of the products and services we saw on display this year in the exhibition:

ADIAnalog Devices introduced the ADMV1013, a wideband, microwave upconverter optimized for point to point microwave radio designs operating in the 24 GHz to 44 GHz frequency range. The upconverter offers two modes of frequency translation. The device is capable of direct conversion to RF from baseband in-phase quadrature (I/Q) input signals, as well as single-sideband (SSB) upconversion from complex intermediate frequency (IF) inputs. The baseband I/Q input path can be disabled and modulated complex IF signals, anywhere from 0.8 GHz to 6.0 GHz, can be inserted in the IF path and upconverted to 24 GHz to 44 GHz while suppressing the unwanted sideband by typically better than 26 dBc.

ADI also introduced a new solution for mmWave 5G with the highest available level of integration to reduce design requirements and complexity in the next generation of cellular network infrastructure. The solution combines ADI’s advanced beamformer IC, up/down frequency conversion (UDC), and additional mixed signal circuitry. This optimized “Beams to Bits” signal chain represents a unique set of capabilities only available from ADI. The new mmWave 5G chipset includes the 16-channel ADMV4821 dual/single polarization beamformer IC, 16-channel ADMV4801 single-polarization beamformer IC and the ADMV1017 mmWave UDC. The 24- to 30-GHz beamforming + UDC solution forms a 3GPP 5G NR compliant mmWave front-end to address the n261, n257 and n258 bands. The high channel density, coupled with the ability to support both single- and dual-polarization deployments, greatly increases system flexibility and reconfigurability for multiple 5G use cases while best-in-class equivalent isotropically radiated power (EIRP) extends radio range and density. ADI’s heritage in mmWave allows customers to take advantage of world class applications and system design to optimize complete lineups for thermal, RF, power and routing considerations.

CMTCopper 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. Copper Mountain Technologies also offers a customizable multi-port network analysis solution that builds on the capabilities of the 1-Port USB vector network analyzers (cable and antenna analyzers) named RNVNA.

Users can also define mechanical calibration standards from any vendor and use with all VNAs, avoid common errors with a simplified calibration using intuitive GUI validate VNA calibration, measure S-parameters and save S2P files, understand measurement results better with advanced visualization and analysis, identify and quantify the individual contributions of uncertainty and display uncertainty boundaries with measurement results

They also updated their VNA calibration kit offering with Characterized Device (CD) fixed-load SOLT cal kits.  CK50-series CD cal kits are composed of individually characterized short, open and fixed load standards. Each kit comes with custom S-parameter files which are used for VNA calibration instead of a generalized polynomial definition, resulting in TRL-like accuracy with fixed-load SOLT ease-of-use. 

They also introduced CK60-series Verification Kits are designed for 1-port and 2-port VNA calibration validation for well-matched and mismatched DUTs. Each kit comes with individually characterized verification standards and is used for calibration validation by comparing the S-parameters of the individual verification standards measured by the user and the S-parameters measured at the factory. When combining the CK50-series cal kits and CK60-series verification kits with MT940-series Insight Calibration and Measurement Software, users will be able to quantify the uncertainty contribution of their calibration kit to their overall measurement uncertainty.
