Abstract

The invention discloses a high-efficiency five-order inverse class F power amplifier. The power amplifier comprises an input fundamental wave matching network, a transistor, a parasitic parameter adjusting network, an inverse class F high-order harmonic impedance matching network, an output fundamental wave matching network and a power supply decoupling bias network. According to the invention, the inverse F-type higher harmonic impedance matching network is adopted to realize the independent and accurate control of the fundamental wave load impedance to the fifth harmonic load impedance of the transistor, compared with a fifth-order F-type power amplifier, the power amplifier has lower DC power consumption and higher efficiency, and the sensitivity of the power amplifier to the on-resistance of the transistor is greatly reduced. According to the high-efficiency five-order inverse class F power amplifier realized by the invention, the harmonic energy loss of the transistor is reduced by utilizing a five-order inverse class F amplification principle, meanwhile, the independent design of each harmonic impedance is realized, the later optimization debugging is not needed, and the design complexity is reduced.

Description

technical field [0001] The invention belongs to the field of radio frequency communication, in particular to a high-efficiency fifth-order inverse class F power amplifier. Background technique [0002] With the popularization of the concept of "green communication", wireless communication systems have higher and higher requirements for "low energy consumption" of radio frequency microwave transceivers. The high-power RF microwave power amplifier circuit at the end of the transmitter consumes more than 70% of the energy in the transmitter, so improving its efficiency becomes the key to "energy saving and emission reduction". Class F or inverse Class F power amplifier is a switching power amplifier. Ideally, its efficiency can reach 100%. The fundamental wave impedance in its output load impedance must meet the optimal load impedance, and the higher harmonic impedance must be open circuit or Short circuit, how to realize high-efficiency class F or inverse class F power amplif...
