Integrated broadband digital receiver

The utility model relates to an integrated broadband digital receiver. The integrated broadband digital receiver comprises a radio frequency preselecting module, a primary frequency conversion module, a secondary frequency conversion module, an A/D acquisition module, an FPGA control module and a high-speed network interface module, and the FPGA control module is respectively connected with the radio frequency preselecting module, the primary frequency conversion module, the secondary frequency conversion module, the A/D acquisition module, and the high-speed network interface module. According to the integrated broadband digital receiver, the radio frequency preselecting module, the primary frequency conversion module, the secondary frequency conversion module, the A/D acquisition module, the FPGA control module, and the high-speed network interface module are integrated on one printed board so that analog links in a system structure are reduced; the digital signal processing technology is employed to process ADC output data, and radiofrequency signal broadband and high-speed real-time processing are realized; the software radio technology is employed, an analog radio frequency front terminal, a high-speed digital signal processing core, and a network control interface with the highest linearity are integrated so that the integrated broadband digital receiver is realized.
