Title:
RADIO-FREQUENCY POWER AMPLIFIER BASED ON TRANSFORMER MATCHING NETWORK
Document Type and Number:
WIPO Patent Application WO/2023/040201
Kind Code:
A1
Abstract:
Disclosed in the embodiments of the present invention is a radio-frequency power amplifier based on a transformer matching network. The radio-frequency power amplifier comprises an input matching network, a first-stage one-way amplification circuit, a first inter-stage matching network, a second-stage two-way amplification circuit, a second inter-stage matching network, a third-stage four-way amplification circuit and an output matching network, which are connected in sequence, wherein the first inter-stage matching network comprises a first transformer T1, the second inter-stage matching network comprises two second transformers T2, and the output matching network comprises two third transformers T3 and a fourth transformer T4. Transformer matching is utilized in both inter-stage matching and output matching, such that the layout area is effectively reduced, and no extra insertion loss is brought about; and the effect of optimizing the gain and the output return loss is significantly improved.
