摘　　要：介绍1种一体化和差组合网络，将4个3dB带状线耦合电桥组合起来应用于馈源网络中形成和差，省去电缆配相的过程，结构紧凑简单，易生产和调试。本文分析了3dB电桥的原理和性能，将其组合成一体化和差网络，并通过仿真和实测验证了其性能。The paper introduces a kind of integrated sum-difference network, which is composed of four stripline-structured 3 dB hybrids. It can be used in feed network to form sum and difference, which leaves out the phase compensation, and its structure is smaller and simpler, and it is easier to manufacture and test. We analyzed the theory and performance of the stripline-structured 3 dB hybrid, then made up the integrated sum-difference network, at last we verified its performance through experiment and simulation.
