Abstract

A hybrid continuous extended-mode inverse class-F power amplifier is designed with band-pass filtered matching networks to match transistor inputs. This design methodology increases the impedance space by incorporating free factors into the current equation of the traditional inverse class-F power amplifier (PA). The suggested matching network in this article is a reliable alternative to the commonly used low-pass structured matching network, and this synthesis method simplifies the deployment of the distributed network compared to the LC low-pass network. High efficiency is guaranteed by the constructed output band-pass matching network. To verify the validity and superiority of this design method, a broadband power amplifier operating at 2.6-4.0 GHz was designed and fabricated. Largesignal measurement results indicate that the drain efficiency (DE) ranges from 60% to 81%, 40-42.3 dBm output power, and 10.5-11.5 dB power gain across this frequency range.
