HIGH POWER DENSITY STUDY.
Abstract
Considerations for selecting the optimum microwave transmitter tube(s) for a limited war radar transmitter operating in a burst mode without benefit of forced air or liquid cooling are investigated. Both hardware and system considerations are covered. Electrical and thermal techniques used in microwave tubes and the application of these techniques to the various classes of tubes are described. Aids in selecting the optimum operating frequency band and the synthetic generation of high pulse power are given. The manner in which average power capability and efficiency vary as a function of the burst period is illustrated. A comprehensive tube survey resulted in the selection of four coherent transmitter amplifier chains, one each in P, L, S, and C-bands, which meet the requirements of PR-A-1109. For comparison an L-band system with optimized parameters and a C-band magnetron system are also described. The transmitter designs are such that weight has been kept below 100 lbs, and over-all efficiency greater than 45% in several of the designs has been achieved. (Author)
