摘要

提出了一种易于实现的高信号隔离度四端口双模双工器。通过仅使用一个谐振器滤波器拓扑结构，可以实现Rx和Tx模块之间具有高信号隔离的紧凑型双模双工器。两个背靠背双模双工器在一个支路中具有180°相移。高隔离可以通过幅度和相位消除技术来实现。延迟传输线可以通过移相器容易地实现。模拟和测量的四端口双模双工器是在1.95的Rx/Tx中心频率下设计的 GHz和2.14 GHz。Rx/Tx双模双工器器件的测量结果为47.1 dB Rx/Tx隔离。该四端口双模双工器实现了24.1以上的隔离（S32） dB。

Four-Port Dual-Mode Diplexer with High Signal Isolation

An ease of four-port dual-mode diplexer with high signal isolation is presented. A compact dual-mode diplexer with high signal isolation between the Rx and Tx modules is achievable by only using one resonator filter topology. Two back-to-back dual-mode diplexers have a 180° phase shift in one branch. The high isolation can be achieved by amplitude and phase cancellation technique. The delayed transmission line can be easily achieved by the phase shifter. The simulated and measured four-port dual-mode diplexers are designed at the centre frequency of Rx/Tx at 1.95 GHz and 2.14 GHz, respectively. The measured results of Rx/Tx dual-mode diplexer devices are presented with 47.1 dB Rx/Tx isolation. This four-port dual-mode diplexer achieves the isolation (S32) of more than 24.1 dB when compared with the conventional three-port dual-mode diplexer structure.
