Abstract

An X-band monolithic three-stage low noise amplifier (LNA) employing series feedback has demonstrated 1.8 dB noise figure with 30.0 dB gain and an input VSWR less than 1.2:1 at 10 GHz. The key to this design is using monolithic technology to obtain an exactly repeatable series feedback inductance to achieve a simultaneous noise match and input VSWR match.

x波段单片串联反馈LNA

采用串联反馈的x波段单片三级低噪声放大器(LNA)在10 GHz时的噪声系数为1.8 dB，增益为30.0 dB，输入驻波比小于1.2:1。本设计的关键是利用单片技术获得精确可重复的串联反馈电感，以实现同时匹配噪声和输入驻波比。
