Space Grade Screening
Renaissance Electronics has been designing and building Circulators and Isolators to meet the demands of both Commercial and Defense satellite applications for decades. All of these have been designed and tested to our unique customer requirements. This has expanded to include may other passive elements such as power dividers, filters, mixers etc.
As the market has transformed with the number of satellites increasing, REC has adapted to this market by recommending a standard screening process that will cover many if not most of your requirements.
What is shown below is a common screening process often used at REC. This can be adapted to your unique requirements as needed.
