给出了较宽通带对称双工器的直接设计方法。基于同一个低通原型滤波器的两个带宽相同但中心频率不同的带通滤波器 ,根据给出的直接计算公式调整其部分元件值后可直接连接 ,得到性能良好的双工器。
The direct design method of wideband passband symmetric diplexer is given. Based on the same low-pass prototype filter, two band-pass filters with the same bandwidth but different center frequencies can be directly connected according to the given direct calculation formula to obtain a good duplexer.
