| Abstract: | To wideband signals demodulation in Ka-band, high speed data demodulator based on RF direct demodulation is presented. Frequency conversion direct by six-port, parallel carrier recovery, parallel clock recovery and parallel channel equalizer in FPGA are used to realize High speed data demodulation on Ka-band . Test result shows high speed data transmission demodulation with information rate 2400Mbps is realized on 28GHz , and demodulation loss is less than 2dB. |
