摘要
着重分析了信号通过无源器件魔Ｔ合成与分配的幅度、相位和频率特性。在此基础上，提出了利用魔Ｔ实现多原频率组合与冗余的几种实用结构．它与以往流行的利用开关在源与源之间直接转换相比，无论在源的有效利用上，还是在保持信号的不中断和相位、频率的连续性方面，都呈现出比较突出的优点．
The hybrid tee is a four-ports passive element.Summation or subtraction of two signals can be completed by this device. Amplitude-phase-frequeney properties of the comb ined signal are analyzed. Several examples for the combination and redundance structures of the frequency sources are preseted. They have many advantages in stability and reliability,comprared to the traditional switch control systems.
