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