Broadband highly efficient continuous inverse class-F power amplifier and design method thereof

Abstract

The invention discloses a broadband highly efficient continuous inverse class-F power amplifier and a design method of the continuous inverse class-F power amplifier. The power amplifier comprises five high-low impedance transmission line type input matching circuits, six high-low impedance transmission line type output matching circuits, an adjustable input feed network and a broadband output feed network. Based on the improved simple real frequency technique matching algorithm with harmonic control, the input and output impedance of the power amplifier is subjected to broadband matching, and the high-efficiency working of the broadband highly efficient continuous inverse class-F power amplifier is realized. The design method improves the efficiency, while the defect that the dielectric constant of a baseplate material in the general low-pass filter prototype design method is limited is avoided, and the continuous inverse class-F power amplifier which can be applied to plates with the higher dielectric constant is provided. Under the application background of high-efficiency broadband power amplifiers and aiming at the comprehensive demands of the broadband high-efficiency design method, the broadband highly efficient continuous inverse class-F power amplifier has the advantages of being simple in structure, compact in size and wide in applicability.

Description

technical field [0001] The invention relates to a broadband high-efficiency continuous inverse class-F power amplifier and a design method thereof, belonging to the technical field of wireless communication. Background technique [0002] With the rapid development of a new generation of wireless communication systems, the demand for higher data transmission rates and richer service content has made the bandwidth of baseband signals wider and wider, and even the baseband signals in LTE-Advanced communications in 4G have already Up to 100MHz; in addition, the compatibility of multiple communication modes and the requirement of multi-band work put forward higher requirements for the bandwidth of the wireless communication system. As an important part of the wireless communication system, the broadband characteristic of the high power amplifier has become an important index to measure the performance of the power amplifier. [0003] On the other hand, in the face of business ne...
