DOHERTY POWER AMPLIFIER APPARATUS AND POWER AMPLIFICATION METHOD
摘要
<p>Disclosed are a Doherty power amplifier apparatus and a power amplification method. The apparatus includes a main power amplifier apparatus and an auxiliary power amplifier apparatus, wherein the main power amplifier device performs signal power amplification using a high voltage heterojunction bipolar transistor (HVHBT) device, and the auxiliary power amplifier apparatus performs signal power amplification using a high electron mobility transistor (HEMT) device. The present solution can significantly improve the power amplification efficiency of the entire Doherty power amplifier.</p>
