摘　　要：提出一种Ka波段脉冲功率放大器的设计方法,重点针对高速双脉冲调制开关电路进行了论述,同时针对可靠性开展了热设计,对样机进行了测试,脉冲功率信号上升、下降沿时间≤4.0ns,可靠性设计满足一级降额要求,各项主要指标满足设计要求,验证了设计方法的合理性和可行性。This paper presents a design method of Ka-band pulse power amplifier,emphatically discusses the high-speed double-pulse modulation switch circuit,at the same time performs thermal design in view of reliability,tests the prototype.The result shows that the rise time and fall time of the pulse power signal are less than 4ns,and reliability design meets the qualification of the senior downgrade,and each main index satisfies the design requirement,which validates the rationality and feasibility of the design method.
