The design of a broadband high-efficiency class-E power amplifier (PA) using a 0.8-m PHEMT device is presented. In order to achieve broadband operation, a T-transform output-load network is used. Power-added efficiency (PAE) greater than 50% is achieved over a frequency bandwidth of 49%. The simulat

## Abstract In this article, we propose a highly linear analog predistortion power amplifier (PA). To successfully use the analog predistorter, memory effects of the PA are significantly reduced using drain bias circuit with high drain bias voltage as well as widened ฮป/4 bias line and several decou
