This report describes the design and development of a broadband, high power, low-pressure micro wave switch. Pertinent design information, particularly as it relates to electrical performance and mechanical fabrication is presented, as is detailed information on the experimental measurement facilities. Particularly significant results derived are the magnitude of the peak pulse microwave power that the gaseous switch can control and the rapidity of switching action. Other features are the low insertion loss with the device either in the active or passive state. Good isolation was achieved over the entire range of rated power level. The following experimental results were achieved 1 Rf power switched, up to a megawatt 2 Switching Time, - 30 nano seconds 3 Isolation, - 30 decibels 4 Arc Loss, - 0.9 decibels 5 Cold Insertion Loss, 0.2 decibels 6 Spike Leakage, - none 7 VSWR over C band, - 1.2 max 8 Recovery Time, 30 microseconds and 9 RF Pulse Width, - up to 1 microsecond.
