en.Wedoany.com Reported - Germany's Rohde & Schwarz showcased a series of RF and microwave test solutions at IMS 2026, covering multiple application scenarios including broadband amplifier measurement, vector network analyzers, non-terrestrial network communication testing, electronic warfare countermeasure analysis, and broadband amplifiers. The exhibits at the company's booth focused on real-world testing scenarios, including broadband signal analysis, pulse and millimeter-wave measurements, satellite communication link evaluation, DRFM-based countermeasure testing, and multi-application RF characterization.
Application Engineer Tosin Adebayo demonstrated a broadband amplifier measurement setup. This setup used the R&S SMW200A to transmit a 100 MHz OFDM signal to two coupled amplifiers, simulating modern communication conditions with complex broadband modulation. The input and output signals were simultaneously analyzed by the R&S FSWX dual-port signal and spectrum analyzer, measuring input EVM, output EVM, and residual EVM, enabling engineers to directly compare signal quality before and after amplification and identify distortions introduced by the amplifier.
Product Manager David Skoog introduced the R&S ZNB3000 vector network analyzer. As part of an economical pulse and millimeter-wave test setup, this instrument offers frequency coverage up to 54 GHz, equipped with four ports and high-speed measurement capabilities suitable for production environments. The demonstration showcased the simultaneous testing of two amplifiers using the instrument's multi-port capability: one setup performed pulse measurements on an amplifier around 50 GHz, comparing continuous wave and pulse signals to evaluate compression behavior and reduce thermal stress; the other port was paired with a millimeter-wave frequency extender covering 70 GHz to 110 GHz to measure a waveguide amplifier. This demonstration supported frequency extension up to 330 GHz.
Business Development Manager Jay Osselburn showcased the BBA300 dual-band broadband amplifier covering 380 MHz to 18 GHz. This all-in-one solution combines dual-band architecture with broadband performance, offering one of the widest continuous frequency ranges in a single unit. The BBA300 is suitable for scenarios requiring broadband signal amplification across multiple frequency bands in RF, microwave, communications, aerospace, defense, and test applications.
Regional Application Engineer Kevin Latonick demonstrated a non-terrestrial network test setup focused on uplink communication scenarios. This setup used the R&S SMW200A vector signal generator paired with the R&S FSW signal and spectrum analyzer to simulate a high-capacity cellular link between a device and a satellite. The setup transmitted a 500 MHz bandwidth signal with 4096-QAM modulation, achieving an error vector magnitude of 0.78% under normal conditions with clear constellation points. When the signal power was reduced by 10 dB, the constellation became significantly distorted, with EVM rising to 1.78%, exceeding acceptable limits, demonstrating the impact of signal degradation on data accuracy and system performance.
Application Engineer Joseph Faulkner demonstrated a countermeasure test setup using the R&S FSWX signal and spectrum analyzer, focusing on evaluating DRFM-based electronic warfare responses. This setup enabled real-time comparison between incoming threat radar signals and response signals. The demonstration highlighted countermeasure techniques such as range gate pull-off by analyzing changes in pulse repetition interval and signal amplitude, and showcased parameter trends and inter-pulse phase coherence measurements.
Rohde & Schwarz also demonstrated a ZNA vector network analyzer setup equipped with a downconverter, capable of performing P1dB compression testing, noise figure measurement, group delay analysis, gain and conversion measurement, and active device characterization on amplifiers, mixers, and frequency conversion devices. By combining the ZNA with the downconverter, this setup simplified the measurement workflow, enabling extensive testing without the need for multiple instruments. This solution supports applications such as amplifier testing, mixer characterization, RF and microwave design, aerospace and defense systems, and radar and communication equipment.
IMS 2026 is the world's leading RF and microwave conference, bringing together thousands of industry professionals globally to explore the latest technologies, tools, and technical developments.
