LIMITED WAR RADAR TECHNIQUES SOLID STATE RADIATING TRANSMITTER.

Abstract

The object of this program was to develop a solid state transmitter module with a peak power of 200 watts and a projected design for a broadside array using these modules. The approach selected was to parallel sixteen RCA Type TA2675 overlay transistors in parallel and combining their power outputs by means of strip transmission line hybrid junctions to a radiating element integral with the module. The experimental model delivered a peak power output of 272 watts at 432 MHz and when operated at the 200 watt level had an output variation of less than 1.5db over a 20 MHz band. The prime advantage of the solid state module is the elimination of the requirement for a modulator, since the transistor amplifiers are designed to draw negligible current in the absence of r.f. drive power, they can be operated from an unswitched power source.
