报道了Ku波段30W脉冲微波功率放大器模块的研制.模块的微波放大链路由5级固态功率器件级联构成,采用新颖的双层腔体结构,消除了低频电路与高频电路的互扰.针对Ku波段内匹配MESFET设计了双段式偏置电路,有效抑制了低频振荡.在脉冲重复频率3kHz,占空比10%下,模块在13.5~14.0GHz工作频段内的功率增益GP≥44dB,输出脉冲峰值功率Ppk≥30W,总效率η≥13%(A类放大状态). The development of the Ku-band 30W microwave power amplifier module is reported.The microwave amplification chain of the module consists of five cascaded solid state power devices, and the novel double-layer cavity structure eliminates the mutual interference between the low-frequency circuit and the high-frequency circuit. A dual-stage bias circuit is designed for the matched MESFET in the Ku band, which effectively suppresses the low-frequency oscillation.Under the pulse repetition frequency of 3kHz and the duty ratio of 10%, the power gain of the module in the 13.5-14.0GHz band is GP≥44dB, Output pulse peak power Ppk ≥ 30W, the total efficiency η ≥ 13% (A type of amplification state).
