DEVELOPMENT OF TRANSMITTER TUBE FOR TROPOSCATTER APPLICATIONS.

Abstract

The program objective is to determine the design criteria for a highly efficient (50% overall including focusing and cooling power) 10 kW CW traveling-wave amplifier at C-band and to demonstrate a feasibility model of the device. This amplifier is to have 11 dB of gain to boost the output of existing 1 kW troposcatter systems using power generators readily available. Techniques to improve the efficiency by reducing the power necessary to cool the device are an integral part of the program. Improvement in basic tube efficiency is to be accomplished by voltage jump tapering -- a recently developed technique which has demonstrated over 60% efficiency in an experimental traveling-wave amplifier. Cooling efficiency will be improved by utilizing vapor phase (nucleate boiling) cooling, eliminating the need for a coolant pump. (Author)
