Reconfigurable continuous Class-F power amplifier using tunable output matching network

The design of a reconfigurable continuous Class-F power amplifier (PA) is presented in this paper. A varactor-based output matching network is used to design the reconfigurable continuous Class-F PA. By employing the CREE 10W GaN HEMT device CGH40010F, the design is verified by simulation. The layout simulation results show that more than 50% efficiency is obtained from 0.9GHz to 1.45GHz. In each reconfigurable band with a bandwidth of 200MHz, the power gain is within 10.6±1.0dB.
