摘要

本文介绍了射频专用硅技术BÌCMOS9MW中协同设计的低噪声放大器(LNA)和偶极子天线。LNA是一个基于SiGe:C 130 nm HBT的两级级联码，优化了最大增益。该天线采用偶极子设计，以匹配LNA输入阻抗并最大化辐射图。两者都直接在硅芯片上协集成。该电路专门用于80GHz的汽车雷达应用。协积LNA的测量结果显示增益和NF分别为26dB和5dB，功耗为20mW，而天线的模拟增益为0dB。

80 GHz co-designed LNA and antenna for automotive radar

Co-designed Low Noise Amplifier (LNA) and dipole antenna in a RadioFrequency (RF) dedicated silicon technology, BÌCMOS9MW, are presented in this paper. The LNA is a two-stages cascode based on a SiGe:C 130 nm HBT optimized for maximum gain. The antenna is a dipole designed to match the LNA input impedance and maximize radiation diagram. Both are co-integrated directly on the silicon chip. The circuit is dedicated to automotive radar applications at 80GHz. The measurement results of the co-integrated LNA exhibit a gain and NF of 26dB and 5dB respectively with a power consumption of 20mW, while the antenna shows a simulated gain of 0dB.
