本文提出了一种用于77 GHz信号到达角检测的集成六端口接收机前端。该电路的应用是测向、汽车雷达校准或高精度工业雷达。测量原理是基于两个入射信号的被动叠加和功率检测。该电路具有两个输入放大器、一个宽带无源六端口网络和四个功率检波器。该集成电路在5 V电源电压下的功耗为95 mW。该器件采用200 GHz fT SiGe双极工艺制造，占地面积仅为1028 × 1128 μm2。该电路工作在75 GHz至84 GHz的3 dB带宽内，在80 GHz时的响应度为152 kV/W。提出了一种简单的校准方法，并针对不同的频率值计算了所有的校准参数。
In this paper an integrated six-port receiver front-end for angle-of-arrival detection of 77-GHz signals is presented. Applications of the circuit are direction finding, automotive radar calibration, or high precision industrial radar. The measurement principle is based on passive superposition of two incident signals and power detection. The circuit features two input amplifiers, a broadband passive six-port network, and four power detectors. The integrated circuit has a power consumption of 95 mW with 5 V supply voltage. It is fabricated in a 200-GHz fT SiGe bipolar technology and occupies only 1028 × 1128 μm2. The circuit operates in a 3-dB bandwidth from 75 GHz to 84 GHz and has a responsivity of 152 kV/W at 80 GHz. A simple calibration method is proposed and all calibration parameters are calculated for different frequency values.
