| Abstract: | This report describes a compacted K-band double stage MMIC broad-band PA(power amplifier).The PA has been fabricated on advanced 0.25 μm power pHEMT process.At 21～29 GHz,the PA has 21 dBm output power at 1 dB gain compression point when Vd=6 V,Vg=-0.25 V,Ids=111 mA.It also has small signal gain of 13±1.5 dB.Its VSWRs are below 3 and 1.7 respectively for input and output ports.It is convenient to use with good reliability and consistency.The chip dimension is 1 mm×2.5 mm×0.1 mm.In addition,we give a full layout EM simulation solution,and we conclude the similar results between EM simulation and measurement. |
