摘　　要：基于实际应用需求,采用超外差结构设计实现了一款C波段收发信机。收发信机采用异频双工模式工作,收发频带可互换,接收单元具有60 dB自动增益控制(AGC)动态范围,并具有链路增益程序控制功能,发射功能模块饱和输出功率为20 W,饱和状态下具有18 dBc双音互调特性。设计方案经样机验证,性能指标满足设计要求,可为同类型产品设计提供参考。Based on practical application requirements,a type of C-band transceiver is designed with superheterodyne system structure.This transceiver works in duplex mode with interchangeable receiving and transmitting frequency bands.The receiver unit has60 d B AGC dynamic range,and has a remote programmable gain control function.The transmitter unit has 18 dBc two-tone intermodulation characteristic at saturated 20 W output power.The hardware circuit has been completed and the test results meet the system performance requirements.The proposed transceiver can provide valuable reference for design of similar products.
