Millimeter-wave bands are of increasing interest for the satellite industry and under discussion as potential 5G bands. Antennas for 5G applications make use of the shorter element sizes at these high frequencies to incorporate a larger count of radiating elements. These antenna arrays are essential for beamforming operations that play an important part in next…

In this paper, the characterization of mm-wave channel sounders and validation of measurement data are discussed. Suitable procedures and metrics like the dynamic range and the maximum measurable path loss are proposed for this purpose. They are illustrated by using measurement data at 28 and 82GHz from back-to-back measurements in the laboratory as well as…
This application note describes how to generate and analyze wideband digitally modulated signals in the mm-wave range. Measurement results such as error vector magnitude (EVM) and adjacent channel power (ACLR) are shown. Two test setups and their measurement results on a commercial V-band transceiver module are presented
Generation of wideband digital modulated signals in V-band and above is a challenging task and typically requires a set of multiple instruments. This application note looks into the analysis part as well. Latest signal and spectrum analyzers like the R&S®FSW67 are first to allow use in V-band up to 67 GHz without external frequency conversion.…
In the past 12 months, research around 5G wireless communications has gained significant momentum, yet it is still unclear what the new physical layer may look like. This poses a challenge for transceiver components such as filters, mixers and amplifiers. This webinar discusses the associated test and measurement aspects and challenges that have been identified,…
