摘　　要：为实现多模信号合成输出,设计了一种复合巴伦功分器电路。文中分析了双层带状线结构,推导出了其特性阻抗计算公式和复合电路的传输矩阵。仿真和测试结果表明,电路具有较好的双模平衡合成性能,同时次模的两个输出实现了180°相移,并在塔康相控阵天线中得到了成功应用。A two-way power divider circuit is designed to realize the outputs of muhiple modules, in which the structure of two layers eompound-balun stripline is adopted. The formula of the circuit characteristic impedance is derived from calculating the distributing capacitance, as the transmission matrix of compound circuit is given. By the simulation and test, it is shown that the performance of balance synthesis between two modules is agreed with the requirement, and 180 degrees phase difference between two outputs of secondary module is obtained. The circuit has been successfully applied in the TACAN phased-array antenna.
