摘　　要：针对微波接收系统中,采用多级放大器级联导致接收信号幅频特性不理想的问题,首先提出了一种用于补偿递减增益的微带功率均衡器设计方法。该方法运用理论分析设置初值;运用计算机优化确定均衡器结构;通过微带蛇形线结构实现小型化。然后,在充分考虑工程需求及工艺实现难度的条件下,运用此方法设计了一种L波段小型化功率均衡器。测试结果表明,该均衡器满足系统对均衡量、驻波及小型化的要求。对微波接收系统中均衡器的设计有一定指导意义。Aiming at the problem of undesirable amplitude-frequency characteristic caused by multilevel cascade amplifier in microwave receiver system, a design method of microstrip power equalizer using to com- pensate for the decreasing gain is proposed firstly. The initial values are set through theoretical analysis, the equalizer structure is determined by computer optimization and the miniaturization is achieved by the serpen- tine microstrip structure. And then, in full consideration of the technological difficulties and engineering de- mands, a miniaturized L-hand power equalizer is designed. The test result shows that the equalizer meets the equal range, VSWR, and miniaturization.
