Get in this AppNote 2 test solutions from R&S to cope with the 5G FR1 downlink MIMO signal analysis challenges either using R&S®RTP/RTO oscilloscope or R&S®NRQ6 power sensor as RF frontend to capture the signal. The R&S®VSE will work as a post-processing tool for the IQ analysis.

Failure Analysis for Reliable 5G mmWave Infrastructure

In this white paper, learn how failure analysis helps create reliable 5G mmWave network infrastructure, why multiple failure analysis testing processes improve system quality, and which failure analysis techniques are most effective at improving quality and yields of mmWave systems.

GaN Ka-band Amplifiers for Satcom Applications

This white paper offers an overview of the advantages of gallium nitride (GaN) for high and moderate power levels in Ka-band satellite communications applications. The paper includes a discussion of the RF power amplification challenges presented by Ka-band data transmission, including the need for high power transmission, wide bandwidth and high linearity. Altum RF’s family of GaN amplifiers is presented, with illustrations of how these components suit specific scenarios within Ka-band satcom applications. The paper concludes with a demonstration of the importance of accurate modelling of electrical and thermal effects for these applications, given the high power levels and high frequencies required.

Important Concepts for Automating CMT USB VNAs

CMT VNAs are USB-based and do not have built-in computers. There are benefits to having the VNA measurement module separate from the processing module. The USB VNAs must run with an external PC and the VNA to work. You can consider the VNA software as the driver for VNAs.
