A K-Band MMIC Medium Power Amplifier for Automotive Radars

Abstract
This paper describes a compact K-band single stage MMIC broad-band power amplifier (PA).The PA is fabricated in an advanced 0.25μm power PHEMT process.At 21～28GHz,the PA has a 21dBm P1dB(1dB gain compression point) output power when Vd=6V,Vg=-0.25V,and Ids=82mA.It also has a small signal gain of 7dB.VSWRs are below 3 and 2,respectively,for the input and output ports.The chip dimensions are 1mm×1.2mm×0.1mm.In addition,we give a full layout EM simulation solution,which agrees well with the measurement.-
