Pre-launch Testing of Satellite Payload Application Note

At every stage of production, starting from the component design and eventually leading up to the final integration and launching phase, uncountable amount of tests are performed in order to ensure intended performance in all mission-critical aspects. The industry-leading accuracy of Rohde & Schwarz equipment described in this paper raises test yield and is a further means to make payload test more cost effective and reliable. This application note addresses system- and manufacturing engineers by focusing on CCR/CATR and TVAC RF tests of components and functional modules as well as complete satellite communication payloads at prelaunch level.

Design and Production Challenges of Wire-Wrapped Ferrite RF Passives for Broadband Applications

The next generation of wireless and wired communications (S data & video) are reaching ever increasing frequencies and require much greater bandwidth than previous radio delivery systems. As the frequency and bandwidth requirements have risen from hundreds of megahertz to multiple gigahertz, the performance of passives also need to step up to these new performance demands. This article describes the challenges of developing higher frequency and bandwidth wire wrapped ferrite RF passives, as well as some of the ways MiniRF is addressing these challenges and manufacturing ferrites for the next generation of communications technology.
