- Abstract
- A balanced class-E power amplifier (PA) using a push-pull GaN HEMT for high power and high efficiency is represented. For validation, a class-E PA is designed and implemented using a push-pull type GaN HEMT and tested for a single tone of 2.14 GHz. The measured results show that the balanced GaN HEMT class-E PA shows a drain efficiency and power-added efficiency (PAE) of 71% and 67.4% at an output power of 40 W with a gain of 13 dB through the significant harmonic suppression of below -51 dBc.
