摘　　要：本文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 。Explicit design formulas are given for relatively wideband diplexers. By modifying some of the elements according to the explicit design formulas, two bandpass filters based upon same lowpass prototype with same bandwidth but operating different center frequencies can be connected directly into a diplexer with good performance.
