[0053] The ultra-wideband digital satellite beacon receiver based on software defined radio includes: ultra-wideband radio frequency front-end chip AD9361 based on software defined radio, digital signal processing module chip ZYNQ7010 and a power supply module.
[0054] The ultra-wideband RF front-end chip AD9361 amplifies the input intermediate frequency signal according to the frequency control and power control information fed back by the digital signal processing module chip ZYNQ7010, and down-converts the frequency to 0-30MHz zero intermediate frequency I and Q signals through the quadrature mixer , output to the low-pass filter, and perform high-speed AD processing, so that the back-end digital signal processing module chip can work. The digital signal processing module chip adopts the chip ZYNQ7010 of XILINX Company, and the ZYNQ7010 chip has built-in frequency calculation module, power calculation module and control interface module. The clock frequency of ZYNQ7010 is ...
