Abstract :
An 
-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.
