摘要:

根据微波叠加原理、阻抗匹配和相位补偿理论计算出3dB功率分配器的理论数据,再利用高频电磁场仿真软件进行电磁仿真和参数优化。实物测量结果:输入端口的反射损耗RL=-31.12dB;隔离度Iso=-34.35dB;输出端口功分性能为-3.09dB,-3.07dB;相位差1.8°;输入驻波比VSWR=1.070,与理论数据基本符合。

Abstract:

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 VSWRis 1.070. All of the above results show our design is reasonable.
