Abstract

The invention relates to the technical field of microwave, and particularly provides a millimeter wave power synthesis amplifier. The millimeter wave is divided into three paths in equiamplitude by a three-path power distributor of the millimeter wave power synthesis amplifier; the three paths of millimeter waves are transmitted by an input waveguide transmission line in equiamplitude and the same phase to the power amplifier to be amplified; and the amplified millimeter waves are transmitted in equiamplitude to a three-path power synthesizer by an output waveguide transmission line for equiamplitude same-phase synthesis. A six-path power synthesis amplifier can be constructed when a micro-strip probe adopts a double-probe structure. Thus, with the adoption of the millimeter wave power synthesis amplifier provided by the embodiment of the invention, the problem that the convenience can be introduced to certain application situations due to the fact that the binary-power synthesis technology has vacancy in synthesis paths.

Description

technical field [0001] The invention relates to the field of microwave technology, in particular to a millimeter wave power synthesis amplifier. Background technique [0002] With the rapid development of communication technology, data communication capacity such as voice and video is expanding day by day, resulting in a shortage of radio frequency resources. In order to solve this problem, millimeter wave communication has become an excellent solution due to its advantages of wide bandwidth and large communication capacity. Similarly, there is a huge demand for high-power millimeter-wave radar in the fields of civil, military and deep space exploration. [0003] High-power amplifiers are the core of wireless communication transmitters. Electric vacuum millimeter-wave power amplifiers are especially suitable for millimeter-wave transmitters due to their advantages of high power, wide bandwidth, and high gain. Semiconductor solid-state millimeter-wave amplifiers are widely ...
