前言根据海军计划(合同号N00039-79-C-0295),在S波段设计、制造成一个试验用的阴极激励正交场放大管(Cathode-Driven Crossed-Field Amplifier,CDCFA)。其峰值和平均功率达1MW和20kW。在效率高达80％时,标称增益为30dB。工作电压近30kV。阴极与阳极电路间的隔离优于20dB。噪声测量结果表明噪声性能极好。CDCFA已经可靠工作几百小时。就此管来说,
Preface According to the Navy’s plan (Contract No. N00039-79-C-0295), a pilot cathodic-excitation Crossed-Field Amplifier (CDCFA) was designed and manufactured in the S-band. The peak and average power of 1MW and 20kW. At 80% efficiency, the nominal gain is 30dB. Working voltage nearly 30kV. Isolation between cathode and anode circuits is better than 20dB. Noise measurements show excellent noise performance. CDCFA has been working reliably for hundreds of hours. In this regard,
