Test Platform for RF Systems and Implementation Using Planer Technique

Abstract

Abstract: Satellite Communication is performed in various bands of microwave frequency spectrum and such high frequency operation demands a special communication system which provide reliable performance without influenced by frequency band, attenuation factor, environmental loss, modulation scheme etc. which needs complete characterization of card/system behaviour involving testing at ambient, at various environmental conditions including life test at lab environment. Radio frequency cards are highly sensitive and need utmost care while handling to eliminate parasitics and to avoid failures. In order to facilitate and provide appropriate test environment to radio frequency circuit boards, test carrier plates, test jig or test fixtures are evolved.This article details the challenges involved in testing of radio frequency cards, concept of test jigs, implementation strategy etc. further test jig for integrated RF circuit testing is also explained.
