Abstract

The invention relates to a planar four-channel power combining amplifier, belonging to the technical field of communication, which solves the problems of limited adjustable range of amplitude and phase of the existing power combining amplifier and poor combining efficiency. The planar four-channel power combining amplifier comprises a power distributing module, a phase adjusting module, a power amplifying module and a power combining module which are connected in turn. The power distribution module is used for performing power distribution processing on the input signal according to the presetpower distribution demand to obtain four-channel power distribution signal. A phase adjusting module performs phase adjusting processing on four signals after power distribution. The power amplifyingmodule performs power amplifying processing on four signals after phase adjusting, and a power combining module performs power combining processing on four signals after power amplifying, so as to obtain the final signal output satisfying the preset power demand. The invention has the advantages of simple structure, small volume, high system stability and high output power, and the output power can reach more than 10W.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a planar four-way power synthesis amplifier. Background technique [0002] With the rapid development of military and commercial communication systems, the demand for high-efficiency, wide-band, and miniaturized solid-state power amplifiers is increasing day by day. [0003] At present, in microwave monolithic integrated circuits, the output power of solid-state power amplifiers is limited, and power combining technology is widely used to obtain greater output power. Power combining refers to the signal superposition of multiple unit power amplifiers of the same model with a specific phase relationship through the power combining network, so that the power output capability of the power combining amplifier is greatly improved compared with the unit power amplifier. [0004] After years of development and improvement, power combining technology can be divided into chip comb...
