POWER AMPLIFICATION TUBE AND POWER AMPLIFICATION METHOD

摘要

Disclosed are a power amplification tube and a power amplification method. The power amplification tube includes a high electron mobility transistor (HEMT) power amplification core and a laterally diffused metal oxide semiconductor (LDMOS) power amplification tube core which are integrated into the same encapsulation. The present invention should be set as a Doherty amplifier, and the power tube is designed using a revolutionary brand-new way of power amplification tube core combination. Compared with the existing Doherty amplifiers which use LDMOS power amplification tube cores throughout, power amplification with high efficiency can be realized on the basis of ensuring a small volume of power amplification tube.
