In this article, a broadband approach to high-efficiency power amplifier performance, based on the parallel-circuit Class E mode, is discussed. Results for a practical implementation of multi-band and multi-mode handset power amplifiers are shown. Measurements demonstrate the feasibility of the conc
In this paper, a novel diode linearizer to keep the base voltage of SiGe HBT power amplifier (PA) constant in the large-signal region is introduced. The results show that the output P 1dB , and poweradded efficiency (PAE) are improved by 4.9 dBm and 22.8%, respectively. At an input power of 20 dBm,
