W-Band Wireless Signal IF-Conversion Using Antenna-Coupled-Electrode Optical Modulator for Millimeter-Wave Radars

IF-conversion of W-band wireless signals using an antenna-coupled electrode electro-optic modulator and photonic technique is reported. Clear spectrum and spectrogram were obtained with a S/N ratio over 15 dB. This modulator is applicable for the wireless signal detection and calibration of W-band radars and imagers.
