The structure design of 3dB power splitter is finished based on the microwave superposition principle, impedance matching and phase compensation theory. High frequency electromagnetic simulation software HFSS has also been used to simulate and optimize the parameters of the design. The test results of manufacturing device are obtained as below:the reflection loss in input port is-31.12dB;isolation is-34.35dB;the power splitting in output port are-3.09dB,-3.07dB;the phase difference is 1.8°;input VSWR is 1.070. All of the above results show our design is reasonable.
