A 5GHz-Band On-Chip Matching CMOS MMIC Front-End

A 5GHz--band CMOS MMIC front-end is developed,which includes a two-stage power amplifier (PA)with a single-stage push-pull driver (DRV),a three- stage low noise amplifier (LNA),and a transmit/receive (T/R)switch.The high current on-chip matching spiral inductor is used for the on-chip matching PA.On-chip matching configuration enables these circuits to connect internally.The IC performs 14.8dBm transmit power,and 4.1dB receiver noise figure at 5.2GHz
