针对毫米波射频收发前端工作频率越来越高的应用需求,设计了一种工作在V频段的毫米波射频收发前端,用于V频段射频信号的接收及发射功能。该射频收发前端电路复杂,内部包含接收电路、发射电路、频率源电路、电源处理电路及控制电路,具有多功能、高镜像抑制度、低噪声系数、高发射功率的优点。为了实现良好的电性能,该收发前端设计并使用了V频段微带滤波器、V频段微带功分器,V频段四分之一波长短路线等微带电路。收发前端采用了V频段MMIC混合多功能集成技术,可应用于导引头雷达及通信场景,具有广阔的应用前景。

In response to the increasing demand for higher operating requencies of millimeter-wave RF transceiver front-ends,this paper presents the design of a V-band millimeter-wave RF transceiver front-end for the reception and transmission of RF signals in the V-band.The RF transceiver front-end circuit is complex,which includes receiver circuits,transmitter circuits,frequency source circuits,power processing circuits and control circuits,with the advantage of multifunctionality,high image rejection,low noise figure,and high transmit power.In order to achieve excellent electrical performance,the front-and design incorporates kinds of microstrip circuirs such as V-band microstrip filters,V-band microstrip power dividers,and V-band quarterwavelength short-circuit lines.The front-end also utilizes V-band MMIC hybrid multifunctional integration technology,making it suitable for use in guidance head radar and communication scenarios with broad application prospects.
