Bandwidth Optimization of Doherty Power Amplifier Based on Source Converters for 5G Mobile Handsets

In this study, wideband Doherty power amplifiers (DPAs) based on converters comprising one transformer and two capacitors are investigated. Moreover, the parallel and series-type Doherty combiners are investigated. The series-type Doherty combiner is shown to have wider characteristics than the para...
