摘　　要：针对现代雷达系统多功能、高集成、小型化发展的需求,设计了一种应用于有源相控阵天线复杂馈线系统的射频网络。射频网络采用埋薄膜电阻实现隔离功能,与数字电路的一体化设计,提高系统的集成度、稳定性和可靠性。通过高频仿真软件Ansoft HFSS对射频网络建模仿真,射频网络电路与激励器控制电路一体化加工。测试结果表明,射频网络在5.05.8 GHz工作频带内良好匹配,VSWR≤1.3,带内传输特性一致性较好,端口起伏≤0.4 d B,与仿真结果对比很吻合。An integrated RF network module is proposed for the modern active phased array to meet the multi-function and com- pact requirements.The RF network is integrated with the digital circuit to increase the system reliability and stability. The embedded membrane resistance is employed to realize the isolation in the RF net＇work.The integrated RF network and PCB boards are fabricated. The VSWR≤1.3 and ripple factor ≤ 0.4 dB at port are measured over the required bandwidth, which agree well with the calculated results.
