After a couple of re-scheduled dates, EuMW 2021 was finally able to take place April 2-7 at London’s ExCeL convention center. It was only by the great efforts of the organizing committees that it was an in-person event with more than 900 delegates and more than 1000 visitors. While this is down significantly from a normal pre-COVID year, it was still a very respectable event size with more than 150 exhibitors.
The moto for this year’s EuMW is “United in Microwaves,” reflecting the traditional feeling of unity in our community and demonstrates how we can use this conference to re-establish and further develop this feeling within our community of colleagues and fellow professionals. EuMW 2021, as usual, was comprised of three co-located conferences: European Microwave Conference, European Microwave Integrated Circuits Conference and European Radar Conference. There were also special forums for 5G, automotive and defense/space/security along with special sessions and workshops.
Microwave Journal again organized the Industry Sessions at the Defense, Space and Security Forum with a focus on space sensing. There were talks by Rohde & Schwarz, “Toward a Quantum Advantage in Radar,” Analog Devices, “Technology Advancements Enable Next Generation SATCOM and Space-Based Radar,” and Qorvo, “Addressing RF Front-End Challenges for Next Generation Space Applications.”
Microwave Journal visited the following companies at the exhibition and found these featured products on display:
AFT Microwave, based in Backnang, provides microwave components manufactured with its own thin film technology using AlO2, AlN, quartz and ferrite ceramic materials.

BlueShift’s AeroZero® is a polyimide aerogel film manufactured in a roll-to-roll process. AeroZero is a mechanically durable insulating film that is tolerant to very high heat and cryogenic temperatures. Comprised of 80 to 85 percent air an ultra-low density (0.27g/cm3), AeroZero is nicknamed Structured Air. The film thus has high porosity, ultra-low dielectric loss properties and extremely low thermal conductivity. Being a polyimide, AeroZero retains many key properties such as wide operating temperature range (-200°C to +260°C), inherent flame retardancy and chemically resistant. AeroZero® Thermal Barriers provide excellent protection from the increasingly drastic environmental conditions that antennas and radomes experience. The combination of lightweight, thermal insulation and RF transparency makes AeroZero a superior insulator for RF equipment including antenna substrates and radomes. It will be interesting to see how this material can be used for RF applications.

One is the Nano5G, an automated impedance tuner optimized for load-pull measurements at 5G FR2 frequencies. It features a high VSWR, high tuning accuracy and repeatability with direct probe connection with no vibration. Nano5G's industry-leading size and weight allows the tuner to be mounted directly to the probe tip for on-wafer measurements, thereby ensuring the highest tuning range (VSWR, lowest impedance) at the DUT reference plane. The direct connection also reduces the phase skew resulting in a minimize signal distortion and more accurate vector measurements when using wideband modulated signals. Nano5G is the ideal tuner for measurements in the 18 to 50 GHz band, on-wafer and connectorized. Another is the MT1000 and MT2000 mixed-signal active load-pull systems are commercially proven solutions capable of performing load-pull at high speeds of up to 1000 impedance/power states per minute with no limitation on Smith Chart coverage and operating to 67 GHz. The systems are turnkey, one-box load-pull solutions that replace the functions typically performed by passive fundamental and/or harmonic impedance tuners, VNAs and/or NVNAs, analog signal generators, vector signal generators, vector signal analyzers and oscilloscopes and add the capabilities of high speed load-pull measurements and wideband impedance control for modulated signals.
