随着民航系统的高速发展，航管雷达的性能也在日益提升，大功率发射机的运用需要高性能的馈线合成。耐功率高、损耗低、驻波好已是雷达合成器的必要性能。采用带状线T型节3 dB等分电路设计的大功率八合一合成器，各分口采用L29型连接器设计，比传统的N型连接器耐功率性更高，单口可承受6 kW射频功率，八合一合成器总口输出可达45 kW。大功率八合一合成器的设计采用ANSYS HFSS微波射频仿真软件进行仿真优化设计，并加工实物测试其S参数，总口电压驻波≤1.2,各端口损耗<0.12 dB,端口相位一致性较好，并在雷达整机联调中性能良好，表现稳定，很好地满足了航管雷达整机需求。

With the rapid development of the civil aviation system, the performance of air traffic control radars is also improving day by day, and the use of high-power transmitters requires high-performance feeder synthesis.High power resistance, low loss and good standing wave performance are the necessary features of radar synthesizers.This paper adopts a high-power eight-in-one synthesizer designed with a stripline T-shaped joint 3 dB equally divided circuit.Each sub-port uses L29 type connectors, which has higher power resistance than traditional N-type connectors.A single port can withstand radio frequency(RF) power 6 kW,and the total output of the eight-in-one synthesizer can reach 45 kW.The design of the high-power eight-in-one synthesizer adopts ANSYS HFSS microwave and RF simulation software for simulation optimization design, and the real objects is processed, then the S parameters are tested.The total port voltage standing wave ≤1.2,and the loss of each port <0.12 dB.The port phase consistency is good, and the performance is good and stable in the radar whole machine debugging, which meets the requirements of the whole machine for air traffic control radars very well.
