DEVELOPMENT OF TRANSMITTER TUBE FOR TROPOSCATTER APPLICATIONS.
Abstract
The program objective was to determine the design criteria for a highly efficient (50% overall efficiency including focusing and cooling power) 10 kW CW traveling-wave amplifier at C-band designated the 636H 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 were an integral part of the program. The tube empolyed a coupled cavity interaction circuit with a solenoid focused, semi-confined flow electron beam. Improvement in basic tube efficiency was accomplished by voltage jump tapering combined with collector depression. Cooling efficiency was improved by utilizing vapor phase (nucleate boiling) cooling, eliminating the need for a coolant pump. (Author)
