摘要

介绍了一种应用于汽车碰撞预警雷达的12GHz单平衡混频器。仿真结果表明，在12.1GHz频率下，混频器作为本振输入功率为7dBm时的转换损耗为8dB，射频端口的驻波比小于2，低中频和射频中频的隔离度分别大于30dB。满足应用要求。

Design of radar single-balance mixer for intelligent transportation

This paper introduces a 12GHz single-balance mixer applied to automotive collision warning radar based on rat-race structure. The simulated results show that Mixer has 8dB conversion loss as local oscillator input 7dBm power in the 12.1GHz, VSWR of RF port is less than 2, and the isolation of LO-IF and RF-IF are more than 30dB respectively. It will satisfy the requirements of application.
