A class-B push-pull power amplifier based on an extended resonance technique

A class B push-pull power amplifier based on an extended resonance power combining technique is presented. In this design, advantages of push-pull power amplifier, such as doubling power capability and reduced common lead effects, have been achieved with a simple and compact circuit topology. The measured power combining efficiency (PCE) is 93% with 1-dB bandwidth of 12.6% at 1.75 GHz. The measured output power at 1-dB compression is 30 dBm with power added efficiency (PAE) of 59%.
