- A wireless link using quasi-optic transmitter and receiver modules is demonstrated, enabling carrier wave frequency selection within various millimeter-wave bands from E-band to D-band without changing the modules. The photonics-based transmitter driven by an optical heterodyne source uses an ultra-wideband PIN photodiode transmitter module. The receiver is composed of zero-bias Schottky barrier diode envelope detector, with a minimum of -30dBm measured sensitivity leading to a calculated link distance of 15m. Error-free data transmission also enables real-time HDTV streaming.
