A NOVEL CONCURRENT DUAL-MODE CLASS-E PA USING DUAL-BAND STUB TAPPED TRANSFORMER

摘要

A novel concurrent dual-mode class-E power amplifier is proposed. Owing to the stub tapped transformer and compensation inductance, a dual-band output matching network is achieved. Experimental results show the output powers of 38.1 and 38.6 dBm, and the drain efficiency of 63.4% and 65.1% are obtained at 920 MHz and 1200 MHz, respectively.
