Document Type and Number:
WIPO Patent Application WO/2023/226581
Kind Code:
A1
Abstract:
A class-J distributed power amplifier based on harmonic regulation and control, and an optimization method for a class-J distributed power amplifier. The present invention aims to solve the problems of low output power, low efficiency and low gain of a distributed amplifier that are caused by non-uniform driving states, etc. of transistors at different positions in the amplifier. The distributed power amplifier based on harmonic regulation and control in the present invention comprises an input artificial uniform transmission line, an output artificial non-uniform transmission line and a plurality of gain units, wherein two ports of the output artificial non-uniform transmission line are connected to reactance-type terminals, and a gate electrode of a transistor in each gain unit is connected to an RC parallel resonant circuit. In the present invention, on the basis of a load pull method and by using harmonic regulation and control technology, a pure reactance-type terminal network is added to an NDA terminal open-circuit structure, such that characteristics of a port can be improved and the stability of a system can be improved, and a terminal network structure can also be fused with a matching network, thereby increasing the circuit utilization rate, and making the power amplifier have the characteristics of high power, high efficiency, ultra-wideband, high gain, high level of integration, etc.
