摘　　要：本文介绍了一种K波段幅度校正模块的设计,它包括发射通道校正和接收通道校正。其主要功能是提供校正信号、采集校正过程中校正信号的幅度信息并将其传送给控制器,最终由控制器完成幅度误差的解算及校正。在K波段的一个点频频率上,测得发射通道信号测量范围为-15d Bm±20d Bm,接收通道信号测量范围为-40d Bm±20d Bm,功率测量分辨率为0.1d B,带外抑制大于60d B,端口驻波小于1.5。In this paper, design of K-band amplitude correction module is presented. It includes a transmission channel and a receive channel .The module provides correction signal, and measures the amplitude of correction signal. The measurement is sent to controller, and then the error of amplitude is calculated and calibrated. At the dot frequency of K-band, the input dynamic range of input signal of transmission channel and receive channel is -15dBm ± 20dBm and - 40dBm ± 20dBm respectively with the resolution of 0.1dB, out-of-band rejection of 60dB and VSWR less than 1.5.
