Abstract:

In this paper, the transition of micro-strip waveguide, one point eight and one point three waveguide power network introduced. Using the domestic 15 W GaN power single chip, the 8 channel waveguide power synthesis is first designed, and then the 3 channel waveguide power synthesis is made. Finally, the 24 channel synthesis is composed. In the millimeter wave band 2 GHz bandwidth, the overall 24 channel waveguide power combing network synthesis loss is less than 0.8dB, and the synthesis efficiency reaches 83%. The solves the problem that the efficiency of traditional synthesis circuit decreases with the increase of synthetic network series, and meets the requirements of high efficiency and high power.

Key words: millimeter-wave, micro-strip waveguide switching, one point eight power network, one point three power network, high efficiency, high power
