Title:
TWO-STAGE DIFFERENTIAL POWER AMPLIFIER AND RADIO FREQUENCY POWER AMPLIFIER MODULE
Document Type and Number:
WIPO Patent Application WO/2024/087851
Kind Code:
A1
Abstract:
A two-stage differential power amplifier (100) and a radio frequency power amplifier module, wherein the two-stage differential power amplifier (100) comprises, successively connected, a signal input end (RFin), a driving stage power unit (2), an amplification stage differential power unit (3), an output synthesis unit (4), and a signal output end (RFout); the amplification stage differential power unit (3) comprises a differential unit (31), a first final-stage power unit (32), a second final-stage power unit (33), a first capacitor (C04) and a second capacitor (C05). The two-stage differential power amplifier (100) can reduce the influence of a base-collector capacitor on the first final-stage power unit (32) and the second final-stage power unit (33), thereby improving the circuit gain effect of the two-stage differential power amplifier (100).
