Attending EuMW 2024? The Demos in Booth #113J Will Drive Your T&M Success

The Paris Expo Porte de Versailles is packed with various products and solutions for Europe's premier RF, microwave, radar, and wireless event – European Microwave Week (EuMW) 2024. From September 24 – 26, attendees can walk the show floor, talk with exhibitors, and view the latest in RF and microwave technology.

Maury Microwave experts are at the event in Paris ready to discuss the best-in-class solutions featured in six exciting product demonstrations at booth #113J. From real-time phase noise analysis to 65 GHz noise parameters extraction, this blog post will review all the demos Maury Microwave is showcasing at EuMW 2024.

Qualifying LO Substitution Phase Noise Improvements

In an EuMW demonstration, the HSY9000A Series Multi-Channel RF Synthesizer showcases its capabilities as an ideal local oscillator (LO) substitute. A system's LO often introduces phase noise, especially in communications systems using higher-order modulation schemes. A constellation diagram's symbol positions start to distort under these conditions, even crossing over adjacent decision boundaries. Oftentimes, testing an LO requires LO substitution, where a signal generator such as the HSY9000A is used in its place.

The setup also features the HA7062D for highly reliable, extremely fast, real-time phase noise measurements.

On-Wafer Passive Load Pull for 5G FR2

Booth #113J features a vector-receiver source-pull and load-pull setup that utilizes two Nano5GTM automated impedance tuners to manipulate source and load impedances and optimize the performance of a high-frequency, high-power device. The tuners in this on-wafer passive load pull demonstration for 5G FR2 have a compact design for direct probe connection, which shortens the physical distance between the tuner and DUT. With the Nano5G automated impedance tuners, users can minimize phase skew, reduce insertion loss, and maximize control over a larger area of the Smith Chart, among other key benefits that enhance measurement accuracy and reliability.

Wideband Impedance Control at 5G FR2

Enabling the optimization of amplifier linearity and efficiency for high data rate wireless applications, the "Wideband Impedance Control at 5G FR2" demonstration uses the MT2000 mixed-signal active load pull system. The turnkey one-box load pull solution will showcase fundamental frequency modulated load pull of 20 impedance states and power sweep at 26 power levels. All impedances over the modulated bandwidth of 200 MHz are set to a single impedance state.

Cryogenic Noise Parameters

Noise occurs naturally in active devices or circuits, limiting the level at which a signal remains distinguishable and useful for its intended application. Circuit design, therefore, must prioritize noise mitigation. While noise figure is typically measured in a 50-ohm environment, a device’s noise figure varies with the presented source impedance and is expressed through noise parameters. These measurements are crucial in low-noise amplifier (LNA) design using highly mismatched devices, especially in applications such as quantum computing and radio astronomy that require advanced noise parameters under cryogenic conditions.

65 GHz Noise Parameters

Noise parameters for LNA design are also critical in high-frequency applications that operate at lower power levels, which is highlighted in a 65 GHz noise parameters extraction demonstration at EuMW 2024.

The demo uses a MT7553C01 noise receiver module (0.1 GHz – 65 GHz) in a broadband noise parameter system. Featuring an integrated downconverter, bias tees, LNAs, and RF switches, the MT7553C01 connects to the DUT output, reducing the total system noise figure and enhancing noise parameter measurement accuracy.  

Active Load Pull for 6G and Sub-THz Frequencies

Want to see how to perform active load pull for 6G and sub-THz frequencies? We have a demonstration just for you at booth #113J that centers around the MMW-STUDIO – a software suite provided by Vertigo Technologies that enables power and phase control at the DUT reference plane through the extenders. The setup performs a power-controlled S-parameter measurement and an active load pull in the WR6.5 waveguide band (110 GHz – 170 GHz) on a waveguide connectorized amplifier. This capability overcomes the limitations of conventional VNA test benches, which struggle with power and phase control in frequencies over 70 GHz.
