The applied research on a high power V-band 55 Gc amplifier chain was divided into two phases. Phase I resulted in the design of a CW 1 watt, 30 db amplifier traveling wave tube designated STV-197. Design studies were performed toward a 50 KW high gain, broadband traveling wave amplifier designated STV-198. No further work on the STV-197 was performed on Phase II and no tubes were built. Phase II efforts were concluded with the construction and testing of three experimental pulse final amplifier tubes, but for a 10 KW reduced objective. The data obtained from one of the experimental tubes indicated promise of meeting the specifications. Mechanical type failures caused the three experimental tubes to fail. There is a need for additional work in the areas of circuit support to maintain straightness, liquid cooling of the circuit, refinement of the rf window for kilowatt power level applications, and reduction of size and weight.
