摘要： A tri-phase combiner/splitter system that has similar advantages to presently available binary combiner/splitter systems which uses quadrature couplers. Notably, the combiner input Voltage Standing Wave Ratio ("VSWR") remains at 1:1 for identical mismatch impedance at the output ports. There is also a complete cancellation of back-door intermodulation components for identical output device nonlinearities. An innovative wideband, 0.degree. three way combiner/splitter is the basic building block of the present invention. To achieve equal port impedances, a new wideband transmission line transformer is used. By using 60.degree. or 120.degree. phase equalization networks at the three, 0.degree. output ports, this device is converted to a wideband tri-phase combiner.For moderate bandwidths, a coupled transmission line version is possible using meandering strip lines in the same fashion used in quadrature coupler design. A new transmission line phase compensation technique is also accomplished using meandering strip lines.

摘要翻译： 三相组合器/分路器系统具有与使用正交耦合器的当前可用的二进制组合器/分配器系统相似的优点。 值得注意的是，输出端口的相同失配阻抗，组合器输入电压驻波比（“VSWR”）保持在1：1。 对于相同的输出设备非线性，还可以完全取消后门互调部件。 创新的宽带0度三路组合器/分路器是本发明的基本构建块。 为了实现等端口阻抗，使用了一种新的宽带传输线变压器。 通过在三个0度输出端口使用60度或120度相位均衡网络，该器件将转换为宽带三相组合器。 对于适度的带宽，可以以与正交耦合器设计中相同的方式使用蜿蜒带状线来实现耦合传输线版本。 新的传输线相位补偿技术也是使用蜿蜒条线实现的。
