Title:
RADIO FREQUENCY POWER AMPLIFIER AND SHORT MESSAGE COMMUNICATION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2023/093350
Kind Code:
A1
Abstract:
Provided in the present invention is a radio frequency power amplifier. The radio frequency power amplifier comprises a front-stage power amplifier, which is used for amplifying a signal of an input end, and then outputting a single-ended signal; a first helix balun, which is used for converting the single-ended signal of the front-stage power amplifier into a differential signal, and realizing equal power division; a final-stage power amplification unit, which is used for amplifying the differential signal which is output by the first helix balun, and then outputting the amplified differential signal; a second helix balun, which is used for synthesizing the differential signal which is output by the final-stage power amplification unit, and then outputting the synthesized differential signal; a balun tuning capacitor unit, which is used for adjusting the output impedance of the front-stage power amplifier and the output impedance of the final-stage power amplifier; and an output matching network, which is used for realizing impedance matching of a signal which is output by the second helix balun, and then outputting the signal. Further provided in the present invention is a short message communication system. Compared with the prior art, the radio frequency power amplifier and the short message communication system in the present invention have a high output saturation power and a strong harmonic suppression capability.
