Title:
MILLIMETER WAVE HIGH-POWER AMPLIFIER CONSTRUCTED BASED ON INTRA-WAVEGUIDE LONGITUDINAL DISTRIBUTED POWER SYNTHESIS
Document Type and Number:
WIPO Patent Application WO/2023/201769
Kind Code:
A1
Abstract:
The present invention relates to the technical field of communications, and particularly relates to a millimeter wave high-power amplifier constructed based on intra-waveguide longitudinal distributed power synthesis, comprising: a distribution unit, wherein the distribution unit distributes a signal inputted by a first waveguide port into a plurality of signals along a waveguide transmission path by means of a plurality of first micro-strip coupling probes, and outputs the plurality of signals; an amplification unit, wherein the amplification unit is electrically connected to the distribution unit, and amplifies the plurality of signals; and a synthesis unit, wherein the synthesis unit is electrically connected to the amplification unit, and the synthesis unit synthesizes the plurality of amplified signals by means of a plurality of second micro-strip coupling probes, and outputs the synthesized signals from a second waveguide port along the waveguide transmission path. The millimeter wave high-power amplifier of the present invention can perform efficient synthesis by means of a frequency band that is high or low, so as to obtain high-power millimeter wave output, is simple in installation and easy to dissipate heat, and can significantly improve the synthesis efficiency and manufacturability of a power synthesis amplifier, and the constructed high-power amplifier has the characteristics of miniaturization, high integration, and all-solid-state.
