Abstract
Receive band filtering between the last two stages of an N-stage power amplifier can reduce the Rx band noise. There are N−1 interstage matching networks interposing N stage amplifiers, where N≧2. The interstage matching networks and stage amplifiers are electrically connected in series. The N−1th interstage matching network includes a receive band reject filter positioned proximate to the output of the N−1th stage power amplifier.
