DEVELOPMENT OF TRANSMITTER TUBE FOR TROPOSCATTER APPLICATIONS.
Abstract
The program objective is to determine the design criteria for a high efficient (50% overall efficiency including focusing and cooling power) 10 kW CW traveling-wave amplifier at C-band and to construct, test and deliver two (2) advanced exploratory development models of 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. The tube employs a coupled cavity interaction circuit with a solenoid focused, semi-confined flow electron beam. Improvement in basic tube efficiency is accomplished by voltage jump and phase velocity tapering combined with collector depression. Cooling efficiency is improved by utilizing vapor phase (nucleate boiling) cooling, which eliminates the need for a coolant pump. (Author)
