Title:
RADIO FREQUENCY POWER AMPLIFIER
Document Type and Number:
WIPO Patent Application WO/2023/040474
Kind Code:
A1
Abstract:
Disclosed in embodiments of the present utility model is a radio frequency power amplifier, comprising an input matching network, a first-stage two-way amplification circuit, an inter-stage matching network, a second-stage two-way amplification circuit, and an output matching network that are sequentially connected in series, wherein the input matching network comprises a first transformer T1, the inter-stage matching network comprises a second transformer T2, the output matching network comprises a third transformer T3, the first transformer T1 is used for converting a single-ended radio frequency input signal RFin into a pair of differential signals and inputting same to the first-stage two-way amplification circuit, the second transformer T2 is located between the first-stage two-way amplification circuit and the second-stage two-way amplification circuit, the third transformer T3 is used for combining the two differential signals into one radio frequency signal and outputting same. In this way, matching difficulty can be reduced, thereby improving the output power of the radio frequency power amplifier.
