摘　　要：微波多层印制技术是一种基于成熟PCB工艺的三维微波电路制造和封装技术。利用该技术,可在同一块印制板上集成多层微波线路和元器件,并提供微波信号的层间互连,实现板卡级的小型化微波组件、部件乃至分机,进而压缩整个通信电子设备、系统的体积。通过一种工作于C频段的基于微波多层印制技术的收、发一体双16路(双4×4)功分馈电网络的研制和测试,分析出基于该种工艺的阵列子阵馈电的一致性情况,并指出了进一步改进的技术措施。该馈电功分网络在免调试的前提下,具有优良的微波性能和较好的通道间一致性,可用于瓦片式相控阵系统的实现。The microwave multilayer technique is developed from mature pcb technics,and can be used in3D mirowave circuits manufacturing and encapsulating.Various transmission lines,components and microwave vias can be integrated in a single board by using microwave multilayer technique,while miniaturized microwave modules,even sub-system can be packaged in board.The size of communication and electronic devices can be significantly reduced by using this technique.A novel transmit/receive dual-16(dual4×4)feed network based on microwave multilayer technique is proposed,designed,fabricated,and tested in the paper,the coherence of different channels are analyzed,while an update method to improve coherence is put forward.The proposed feed network has good microwave performance and channel coherences without any debug procedure,and exhibits distinct potential in realization of tile phased array system.
