Bandwidth Enhancement of GaN MMIC Doherty Power Amplifiers Using Broadband Transformer-Based Load Modulation Network

Bandwidth Enhancement of GaN MMIC Doherty Power Amplifiers Using Broadband Transformer-Based Load Modulation Network

In this paper, we present a bandwidth enhancement technique for monolithic microwave integrated circuit (MMIC) Doherty power amplifiers (DPAs) in wireless transmitters. A broadband load modulation network is proposed by exploiting transformers and output-referred parasitic capacitances of the carrie...
