Abstract :
Development of a 60 dB gain, three-tube chain of forward-wave amplifiers is described. The chain is designed to fulfill state-of-the-art requirements for high efficiency, light weight, and minimum modulator power for use in advanced radar systems. Two 15-dE crossed-field amplifiers are driven by a traveling-wave tube with all stages dc-operated for 10 percent instantaneous bandwidth centered at 3.3 GHz. The TWT is gridded and the CFA´s have beam cut-off electrodes.
