This paper explains the pulsed RF operation of Microsemi pulsed GaN HEMT RF power transistors using as an example the 1011GN-700ELM 1030 MHz Mode-S Enhanced Message Length (ELM) avionics device. General descriptions are presented detailing both the pulsed gate bias operation and the bias sequencing operation of the “pulser” circuit used on the Microsemi evaluation test fixtures.
The primary goal of the MIMO OTA measurement system is to be able to compare Multi-antenna/MIMO devices and algorithms based on their throughput performances when tested against spatial channel models. All critical parts of the mobile terminal design (antennas, RF front-end, baseband processing) are tested in an end-to-end configuration. This document aims to present all the most relevant technical features of the MVG StarMIMO system relative to the MIMO OTA measurement technique with anechoic chambers.
"S" Series Amplifiers Produce Higher Power, Higher Fidelity Signals For Testing Wireless Output Devices
The scope of the subject has expanded in the recent years in terms of its technical evolution and spreading of applications. This application note along with its corresponding white paper 1MA207 show how to use the R&S radar product portfolio to tackle test and measurement tasks in modern radar technology. Target groups are students who want to become familiar with radar issues as well as radar professionals who want to solve certain test and measurement tasks.
Because coaxial cable assemblies are so vital to such a wide range of systems, from rugged ground-based electronic systems to orbiting satellites in space, the selection process for those cables should not be treated lightly. Choosing the right coaxial cable assembly is not a trivial task, but it is one that can be made somewhat easier by better knowing what to look for in a high-frequency or high-speed coaxial cable assembly.
