A demonstrator of DC offset-free direct conversion receiver is presented. The innovative architecture exploits optical domain up-conversion and photonic I/Q demodulation to perform a wideband scanning of the RF input spectrum avoiding bulky multiple crystal oscillators and bandpass filters. Moreover, the scheme provides a total immunity to local oscillator self-mixing and to RF-to-baseband feedthrough...
