为了满足通信系统的需要，本文主要利用最新的介电同轴SIR技术，完成对通信系统微波天线双工器的设计。介电同轴SIR是一种最新的谐振器件，具有实时、高可靠、低功耗和低成本等优点。这种新技术改变了传统双工器的设计方法，可以在较宽频率内高速工作，完成系统的平衡混频，低相位噪声振荡。基于这种新器件，对天线双工器进行设计，对其性能进行分析，发现这种天线双工器具有应用的价值。现实中双工器的改善具有重要意义。

To meet the demand of communication system, this paper introduces the design of microwave antenna duplexer by using the latest resonant device-the medium co-axial impedance resonator. This new technology changes the traditional duplexer design, having the advantages of real-time, high reliability, low power consumption and low cost. The new duplexer can work within a wider frequency range at high speed, finish balanced mixing and low phase noise oscillation. This duplexer design with the new device is of great importance in actual application.
