EDI CON USA 2017 Celebrates High Frequency and High Speed
EDI CON is the first industry event to bring together RF, microwave, electromagnetic compatibility (EMC), electromagnetic interference (EMI) and high-speed digital design engineers and system integrators for networking, product demonstrations, training and learning opportunities. In its second year, EDI CON USA offered a unique combination of training, technical sessions, workshops and panels, with a commercial exhibition not found at similar events. Eight training courses were offered on the first day, followed by technical sessions, workshops/panels, plenary talks and an exhibition with more than 100 companies on the second and third days.
Among several additions this year: the European Radar Summit, High-Speed Design Symposium, Bring Your Own Board (BYOB) Test Kiosk and a Student Scholarship Program. The European Summit was organized by Alfonso Farina, formerly of Selex, and covered various topics like conformal antennas, passive/active radars, high-speed processing for active electronically scanned array (AESA) radar systems and radar trends. Eric Bogatin, Professor at Colorado University and Dean of the Signal Integrity Lab at Teledyne LeCroy, organized a High-Speed Design Symposium that addressed materials properties and simulations for accurately designing robust high-speed channels. Steve Sandler of Picotest organized a kiosk offering free measurement services in the BYOB program. EDI CON USA raffled off two $500 scholarships to students who attended the event and visited three of the major sponsors. The winners were Rebekah Davis from Northeastern University and Ameya Ramdurgkar from the University of Colorado.
Adding to the three days of education, training and networking were the distinguished keynote speakers who addressed the latest engineering trends and challenges, including “in the trenches” stories of design challenges, successes and failures.
Scott McMorrow, CTO for Signal Integrity Products at Samtec, has helped numerous companies develop high performance products, while training signal integrity engineers. He presented “Betting Your Job – Finding Your Voice and Being a Change Agent in a Corporate World.” He discussed how his philosophy has helped develop diverse products, where the potential failure represented $100 million to more than $1 billion.
Dr. Thomas Cameron, CTO for the Communications Business Unit at Analog Devices, discussed the 5G industry’s goals and motivation in his talk “5G in 5 Years – How Will We Get There.” He predicted that connectivity in the future will be like air, available everywhere without any obstacles.
The final keynote talk, “Delivering value, everybody says it, but what does it mean – A look behind the Scenes of Test & Measurement,” was presented by Faride Akretch, segment marketing manager at Rohde & Schwarz.
The four panel discussions were well received:
- The Ferrari of Amplifiers: How can we maneuver around the current challenges facing high performance GaN? The panelists agreed we have not even come close to the power densities possible with GaN technology – it is just a matter of thermal management.
- Look Ma — No Steering Wheel! The State of the Self-Driving Car. Here, the consensus was that a suite of maturing sensor technologies will enable autonomy, yet many social and regulatory issues need to be overcome.
- Bandwidth or Bust – Commercializing 5G mmWave Technology Today. Low cost semiconductor manufacturing and test methods are still not determined that can meet the needs for the mmWave 5G infrastructure, but we are getting close.
- Solid-State RF Energy in 2017: How Far Have Applications Come and What Still Needs to Be Attained? The outlook is optimistic, as 300 W, 70 percent efficiency power amplifier modules have been achieved and potential materials and connectors appear likely to meet the cost goals required for commercialization in the next couple of years.
The exhibition comprised more than 100 companies, featuring many new products in both the RF/microwave and high-speed digital realms. Here are some of the highlights:
Analog Devices (ADI), EDI CON’s Host Sponsor, recently released the AD9375 RF transceiver that operates from 300 MHz to 6 GHz. The AD9375 is the first RF transceiver to incorporate the digital predistortion (DPD) algorithm on-chip – a design breakthrough that reduces DPD power consumption by 90 percent compared to competing solutions. The re-partitioning of the DPD system from the FPGA to the transceiver cuts the number of JESD204B serial data interface lanes in half, resulting in a dramatic power savings particularly as the number of antennas per base station increases from two to 128 in support of pre-5G massive multiple-input-multiple-output (MIMO) radio-channel density requirements. Other benefits include a more compact radio circuit layout, which simplifies routing and system design, reduces base station size and allows designers to use a lower-cost, less complex FPGA. In small cells these benefits allow more frequency bands per cell for increased network capacity, while minimizing the impact to system power consumption and size. ADI was also featuring a complete 24 to 44 GHz radio in 28 nm CMOS. They had configured a full radio transceiver using their baseband and microwave components showing how they can provide the entire signal chain and customize the solution based on the application needs.
John Richardson, president of X-Microwave, was demonstrating X-Microwave’s building block approach to microwave circuit and system development in the Analog Devices’ (ADI) booth. ADI is one of X-Microwave’s partners, recently releasing 250 of their products in the X-MWblock format. Assembling X-MWblock circuit functions from ADI or another of X-Microwave’s partners on a standard grid, designers can quickly prototype a multi-function circuit or subsystem, swapping blocks to optimize performance. Once configured, the components can be packaged in a machined housing for low rate production or, if the volumes are higher, X-Microwave can integrate the functions and customize the packaging.
Rohde & Schwarz, EDI CON’s Diamond Sponsor, announced that the FSW85 signal and spectrum analyzer now provides 5 GHz analysis bandwidth, which is required for analyzing wideband signals such as automotive radar FMCW chirp signals, IEEE 802.11ay signals and 5G waveform candidates. Rohde & Schwarz is addressing the fast-growing demands for characterizing wideband components and systems by introducing the new R&S FSW-B5000 option. In combination with the R&S RTO2064 digital oscilloscope as an external digitizer, the R&S FSW85 signal and spectrum analyzer equipped with the new hardware option provides equalized 5 GHz signal analysis bandwidth. They also recently released an external preamplifier that improves the sensitivity of the R&S FSW85 or another spectrum analyzer. The FSW firmware automatically recognizes the HA-Z24E and loads the calibration data. It is connected to the spectrum analyzer with an USB cable, which also provides a 5 V supply.
Anritsu (EDI CON Gold Sponsor) was showing off the MS2760A, the first handheld millimeter wave spectrum analyzer to provide continuous coverage from 9 kHz up to 110 GHz, positioning it for growing millimeter wave applications such as 5G, 802.11ad, satellite communications and automotive radar.

RF-Lambda (EDI CON Gold Sponsor) featured their new line of solid-state, USB-controlled RF switches and a new series of wideband solid-state power amplifiers (PA), with output power from 50 to 140 W CW. The switches have high isolation, low insertion loss and fast switching speed and cover a broad frequency range. With software provided, controlling the switches is easy, and no DC supply is required because the switches are biased through the USB interface. The switches support applications from the lab bench to production test. The new wideband solid-state PAs are in a standard rack-mountable enclosures with built-in forced air cooling and feature a user-friendly, interactive interface. These amplifiers are used in wireless communications, medical, EMC and applications that require high power over a wide frequency range.
The ANSYS HFSS SBR+ field solver provides the ability for antenna systems designers to model the antenna and its environment before the antenna is built or installed. Some of these environments can be quite large. An extreme antenna-environment scenario might be the interaction of a 77 GHz automotive radar sensor with 300 meters of roadway and buildings, which adds up to an environment spanning 85,000 electrical wavelengths in size. In the ANSYS Electronics Desktop 18.2, the integrated HFSS SBR+ solver now provides a powerful pre-processing feature to show significant anticipated EM interactions posed by the environment: Visual Ray Trace (VRT). With VRT, desingers can visualize the direct paths taken by EM fields radiated by an antenna through an environment, giving insight into multi-path routes, causes of signal delay spread from one antenna to another, hot coupling zones for nearby antennas, shadowed zone locations and indirect radar scattering paths. ANSYS was a Silver Sponsor of EDI CON.
