Design of a Novel Multi-channel Wideband Transceiver
MA Li-k · Telecommunication Engineering · 2014
To satisfy the demand of high speed wideband radio frequency sampling and signal synthesizing in airborne frontend equipment and also solve transceiver isolation with signal processing and limit of transmission bandwidth of traditional solutions,a novel multi-channel wideband transceiver solution is provided. High speed digital-to-analog converter( DAC) and analog-to-digital converter( ADC) working at 500 Msample / s are used. Perfect recovery of data signal at receiver-end is realized through receiving and simulating channel logic interface design. Inter-FPGA data communication between transceiver and signal processor is transferred at 10 Gb / s at most. The true multi-channel wideband transceiver function is realized and it will find wide applications in high speed wideband communications.
