摘　　要：提出了一种可用于雷达的毫米波收发组件的实现方案。组件包括两个几乎完全相同的接收通道和一个发射通道,接收通道采用两次混频将毫米波信号变为50MHz中频,而发射通道则采用两次上变频将50MHz信号变为毫米波频段的信号发射出去。该文分析了收发组件的设计原理,讨论了组件方案选择,并给出了测试结果。收发组件的各项技术指标基本达到设计要求:在10MHz的工作带宽内,连续波发射功率达1W,接收机噪声系数小于4.5dB,接收通道的净增益超过100dB。A millimeter-wave transceiver with two-receiver ways and one-transmitter way is designed. It can be used for a millimeter radar. The frequency of the two-ways receiver is converted to 50 MHz from Ka-band by twice mixing. Whereas in the transmitter way, two up-converters make 50 MHz signal transfer to millimeter-wave band. Based on the analysis about the design principle of T/R moudle and various kinds of scheme, the transceiver is fabricated and tested. The performance of a power output of 1.0 W at Ka-band, a noise figure of 4.5 dB, a receiver gain of 100 dB is achieved.
