HIGH POWER SEMICONDUCTOR PHASE SHIFTING DEVICES

Abstract

Effort was continued to inve tigate microwave phase shifting techniques, excluding ferromagnetic and mechanical methods, to make recommendations for the new phase shifting techniques which provide improved electrical scanning, and to develop models of a phase shifter utilizing these techniques. A 3000 Mc step phase shifter was tested and evaluated. Results obtained included a peak power capability of 5 kw at a 0.5 microsecond pulse length with an average power of 25 watts. Step phase shifts were obtained which could be varied from 0 degrees to 180 degrees while maintaining a transmission insertion loss of less than 0.7 db in both phase states. (Author)
