Abstract:

A MILLIMETER FERRITE SWITCH WAS CONSTRUCTED WHICH PROVIDED VSWs under 1.3 over the 8 frequency band with insertion loses under 1 db and isolation between uncoupled ams of greater than 20 db. Switching times of less than 1 mcrosecond were measured sing a transistorized driver. IMPROVEMENTS WERE MADE IN THE CONSTRUCTION TECHNIQUES SED FOR THE HIGH POWER SOLATOR FIXTURE AND THE EFFECT OF CHANGES IN MAGNET POLE PIECE DESIGN WAS INVESTIGATED. A ferrte pulsed attenuator was constructed having an input VSWR less than 1.31 an insertion loss less than 0.7 db and maxmum attenuation greater than 55 db over the frequency band. Switching times slightly greater than 1 microsecond were obtained with a high voltage supply. An expermental high power circulator was contructed having VSWRs less than 1.231, insertion loss less than 0.9 db, and isolation greater than 18 db over the 8 band. Author
