摘要

本文介绍了一种用于宽带软件无线电系统的低成本开关滤波器组模块的开发。采用6个单极双掷(SPDT)交换网络和4个固定五极边耦合带通滤波器，开发了工作在11~20 GHz频率范围内的四通道开关滤波器组模块，该模块是在输入输出馈线(I/O)中典型的边耦合微带带通滤波器的基础上改进而成的，以获得更好的阻带性能。对滤波器和开关滤波器组进行了理论和实验介绍。

A 11~20GHz Switched Filter Bank for Software Defined Radio System

This paper presents the development of a low cost switched filter bank module for a wideband software defined radio system. The four-channel switched filter bank module operating in the frequency range of 11~20 GHz has been developed using six single-pole double-throw (SPDT) switching networks, and four fixed five-pole edge-coupled bandpass filters, which is modified from the typical edge-coupled microstrip bandpass filter in the input and output (I/O) feeders to achieve the better stopband performance. The filters and switched filter bank are introduced theoretically and experimentally.
