A SOLID STATE DUPLEXER SWITCH FOR HF RADAR

Abstract

A problem area in the operation of the NRL HF radar has been that of satisfactory duplexing at 120 kw average and 5 Mw peak power level. The use of silicon diodes as switching elements in a balanced duplexer has been investigated, with such a system having been in use for over one year. Techniques have been devised for supplying appropriate bias for both transmit and receive periods. The results of the investigation show that the silicon diodes provide an adequate solution to the duplexing problems. Pulse to pulse recovery time and switch impedance jitter are negligible; the recovery time is 300 microseconds and could be further improved.
