Zusammenfassung:The invention provides a broadband Doherty power amplifier with continuous inverse class F and class J mixed. The broadband Doherty power amplifier comprises a broadband Wilkinson power divider, a phase compensation line, a carrier power amplification circuit, a peak power amplification circuit and a broadband post-matching circuit. The carrier power amplification circuit comprises a carrier broadband input matching circuit, a carrier amplifier transistor and an impedance converter; the peak power amplification circuit comprises a peak broadband input matching circuit, a peak amplifier transistor, a peak harmonic control/suppression network, a peak fundamental wave tuning network and a reverse phase compensation line; and the broadband post-matching circuit comprises a carrier harmonic control network and a post-matching tuning network. The carrier amplifier works in a continuous inverse class F mode when input power is saturated, works in a class J mode when input power is back-off by 6dB, and the peak ampli
