摘要

介绍了一种具有三种工作状态的微带可切换滤波平衡器。三种工作模式分别是工作在1.43 GHz和1.76 GHz的双频滤波平衡器、以1.43 GHz为中心的低频滤波平衡器(用于WMTS应用)和工作在1.76 GHz的高频滤波平衡器(用于无线通信)。通过控制加载在双模谐振腔开口处的PIN二极管的电压，可以实现三种工作模式的独立切换。双频带通滤波响应是通过嵌入两对双模谐振器实现的。仿真结果表明，该方法具有良好的性能。

Microstrip switchable filtering balun with three operating modes

A microstrip switchable filtering balun with three operating state is presented in this paper. Three operating modes are dual-band filtering balun operating at 1.43 GHz and 1.76 GHz, low-band filtering balun centering at 1.43 GHz for WMTS application, and high-band filtering balun working at 1.76 GHz for wireless communication. Three operating modes can be independently switched by controlling the voltages of PIN diodes loading at the open-ended of dual-mode resonator. The dual-band bandpass filtering responses are achieved by embedding two pairs of dual-mode resonators. The simulated result shows good performance.
