摘要
针对现代电子对抗设备的大瞬时带宽要求,文中设计了一种瞬时带宽4 GHz的6~18 GHz超宽带T/R组件。采用砖块式多芯片组件(Multi-Chip Module,MCM)和超宽带信号传输等技术实现了T/R组件高集成、小型化和模块化的要求。对T/R组件组成构架、收发通道指标预算、宽带信号传输特性仿真和电磁兼容性设计进行了详细描述。测试结果显示,T/R组件在12 GHz工作带宽内具有良好的性能,发射功率大于35 dBm,接收增益大于20 dB,噪声系数小于5 dB,延时总量达762 ps。
In view of the high instantaneous bandwidth requirement of modern electronic countermeasures equipment,a 6~18 GHz ultra-wideband T/R module with instantaneous bandwidth of 4 GHz is designed in this study.The MCM(Multi-Chip Module)and ultra-wideband signal transmission technologies are used to realize the requirements of high integration,miniaturization and modularization of T/R components.The structure of T/R components,the index budget of transceiver channel,the simulation of broadband signal transmission characteristics and the design of electromagnetic compatibility are described in detail.The test results show that the T/R module has a good performance in the 12 GHz operating bandwidth,the transmit power is greater than 35 dBm,the receive gain is greater than 20 dB,the noise factor is less than 5 dB,and the total delay time is up to 762 ps.
