Abstract:

Two general phase-shifting techniques were investigated, both of which employ semiconductor elements. The first approach is the step or incremental phase-shifting device which provides for discrete changes in phase. The second phaseshifting approach is a continuously variable one which provides for a greater flexibility in phase control. Both the semiconductor material and the circuit problems involved in each of the 2 approaches were further explored in some detail. The present study results indicate that both the desired phase-shifting characteristics as well as power-handling capabilities can be reached. Phase shifters were built for L-band which, for the incremental ype, can handle peak powers in excess of 75 kw, and for the continuous type can handle 2 - 6 kw peak power. Author
