Research and Design of L-Band High Power Miniaturized N-Channel Power Synthesizer

Abstract

Based on the Gysel power divider and strip line, this paper has realized the design of N-way power divider with any power ratio. Using ADS and HFSS simulation software for joint simulation, a 5-way distribution ratio of 1:1:0.7774:0.7774:0.7 power divider is designed, and it can realize high-power use. The test results show that the insertion loss of the power splitter is less than 1 dB, the voltage standing wave ratio (VSWR) of the combine port is less than 2. the VSWR of the input port is less than 1.2. The isolation of the four input ports is greater than 20dB, which fits well with the simulation results.
