摘要
通过精密机加工技术制造了一种具有寄生通带抑制的E波段波导双工器。其仿真性能在71~76GHz,81~86GHz通带内插入损耗小于1 dB,通带隔离度大于60 dB;在142~152GHz,162~172GHz二倍频通带内抑制大于20 dB。实测结果显示该双工器通带内插入损耗最差为0.7 dB;通带隔离度优于60 dB;二倍频处抑制大于20 dB。仿真设计与实测结果高度吻合。该双工器的优异性能确保其适用于5 G通信E波段回传网络中。
An E-band waveguide diplexer fabricated by precision machining with harmonic suppression is presented.The simulation result shows the insert loss in 71-76 GHz and 81-86 GHz pass-band is better than 1 dB.The isolation is greater than 60 dB.In the second harmonic pass-band 142-152 GHz and 162-172 GHz,the suppression is greater than 20 dB.The measured results show the insert loss is less than 0.7 dB in pass-band and the isolation is greater than 60 dB,the suppression of harmonic is 20 dB.Simulation and measurement results match very well.The excellent performance of the diplexer ensures that it is suitable for 5G E-band communication backhaul networks and has a good prospect of engineering applications.
