An RF photonic frontend for multi-channel broadband communication payloads has been proposed to face high frequency satellites challenges demanding higher bandwidth and explosive data bytes. The proposed scheme features broadband, light weight, small size compared with conventional RF frontend in a pure microwave approach. Furthermore, we carry out proof-of-concept experiments and present performance...
A multi-channel high-speed serial data acquisition system based on LVDS interface is introduced. In the system, the FPGA APA300 produced by ACTEL Company used to control the serial to parallel conversion and data caching of multi-channel high-speed serial data. Then the parallel data is collected by the data acquisition card. The system can adjust itself by the standard data source generated by itself...
