【Abstract】 This paper describes a high-gain、10％bandwidth、MW levels、L-band klystron amplifier. The tube(D4038)gives 1. 4MW peak output power with more than 10percent instanteneous bandwidth(at l.5dB), a mininum gain of 47dB and more than 30％ efficiency if the tube operates at around 78.5kV and 44.5A. The paper also describes design of the tube and the success of tube hinges on the technology.The paper especially introduces design of the resonant coupled cavity output circuit(RCCO) and simultaneously gives results of hot-test.更多还原
