L波段集成自检源小型化多通道前端

L-band Miniaturized Multi-channel Front-end of Integrated Self-test Source

L波段射频系统的前端模块,在完成放大滤波功能的基础上,还需要具有产生自检信号的功能,以及与上位机进行通信的能力。为了适应现代社会对设备功能完备、体积小、质量轻的要求,通过选用小型集成化跳频源,将数字控制、接口电路与微波控制电路相集成,将自检功分电路与微波控制电路集成,研制出一款集成自检源的多通道射频前端。在保证原有射频前端放大滤波功能、产生自检信号功能、与上位机进行通信功能的基础上,大幅度地减小了射频前端的体积与质量。通过实物制作与测试,验证了上述设计方法在保证多通道射频前端功能完整性的情况下可以大幅度减小整体模块的体积、减轻模块的质量。

For the front-end module of the L-band radio frequency(RF)system,on the basis of completing the amplification and filtering function,it also needs to have the function of generating self-test signals and the ability to communicate with the host computer.In order to meet the requirements of modern social development for equipment with complete functions,small size and light weight,a multi-channel RF front-end with integrated self-test source is developed by selecting a small integrated frequency hopping source,integrating digital control,interface circuit and microwave control circuit,and integrating self-test signal divider with microwave control circuit.On the basis of ensuring the original RF front-end amplification and filtering function,generating self-test signal function,and communicating with the host computer,the volume and weight of the RF front-end are greatly reduced.Through physical production and testing,it is verified that the above design method can greatly reduce the overall module volume and weight while ensuring the functional integrity of multi-channel RF front-end.
