摘　　要：基于射频多层混压板设计了一款K频段新型相控阵双波束接收组件,在三维结构下通过电容加载技术创新优化设计一分六十四Wilkinson功率合路网络,在具备良好性能指标情况下,相比传统合路网络布阵尺寸更小,在此基础上利用延时补偿技术精准控制组件通道间相位一致性,并在器件密集布局位置设置隔离金属柱排除腔体谐振干扰,实现了组件的高频化、高密度可靠性设计,能够很好地适应高频段下机载工作环境应用需要;在19.6~21.2 GHz设计频段内,一分六十四功率合成网络的输入端口回波损耗值大于18 dB,输出端口和输入端口间插入损耗值小于19.8 dB,具有良好的隔离度和相位一致性;对相控阵组件中的垂直互联结构进行了仿真分析,对传输不连续性结构处进行结构优化,实现了低损耗传输;经测试,在19.6~21.2 GHz频段内,双波束接收组件的驻波比小于1.5,组件单通道增益值大于22 dB,不同通道间相位差小于20°。A new K-band phased array dual-beam receiving component was designed based on the RF multi-layer hybrid board.A one-point-sixty-four Wilkinson power synthesis network was innovatively optimized and designed by using capacitor loading technology in a three-dimensional structure,which had better performance and was smaller in size compared to traditional grid layouts.On this basis,delay compensation technology was used to accurately control the phase consistency between component channels,and the isolation metal columns were set at the dense layout of the device to eliminate the resonance interference of the cavity,realizing the high-frequency and high-density reliability design of the component.The array size was reduced while having good performance indicators,which could adapt well to the application needs of the airborne working environment in the high frequency band.Within the designed frequency range of 19.6~21.2 GHz,the input port return loss value of the one-point-sixty-four power combining network was greater than 18 dB,and the insertion loss value of output port and input port was less than 19.8 dB,with good isolation and phase consistency;The vertical interconnection structure in the phased array component was simulated and analyzed,which optimized the structure of the transmission discontinuity structure to achieve low-loss transmission.After testing,it was found that within the frequency range of 19.6~21.2 GHz,the standing wave ratio of the dual-beam receiving component was less than 1.5,the single-channel gain value of the component was greater than 22 dB,and the phase difference between different channels was less than 20°.
