Abstract

Optimum class-AB power amplifier (PA) operation, with maximum power added efficiency (PAE) and ruggedness can be obtained by proper 2^nd harmonic termination at the in- and output. Implementation in a differential push-pull amplifier for DCS band yields significantly higher PAE and ruggedness even under high mismatch conditions. Various PA implementations using novel balun structures are compared for their performance.
