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.

Radar Echo Generator Application Note

Radar test systems are essential in research, development, production and maintenance of radar systems. Most radar tests are expensive to carry out in the field and have a complicated setup and operation. This application note presents a solution for testing the complete radar system by generating any kind of radar echo signals with arbitrary range, Doppler frequency and Radar Cross Section. The Radar Echo Generator makes it possible to perform real time tests on many applications including aerospace & defense and commercial radar systems.

Making Effective Use of Doherty Architecture

With the evolution of 5G technology, the need for antenna array systems is growing. This increases the demand for efficient power amplifier implementations to support high-density setups. Imagine you could get 60 % more output power, 50 % more bandwith and up to 20 % efficiency gain per amplifier in a MIMO antenna array setup? Would you spend time on rethinking your implementation plans?
