In this paper, we present a compact architecture for a high data rate photonic wireless system operating in the W-band (75-110 GHz). By using a cascaded optical RF and data modulation approach with advanced photonic components as well as radio-over-fiber (RoF) transmission and simple NRZ-OOK modulation format, the system allows flexible adjustment of the wireless RF carrier frequency within the 75-110 GHz (W-band). In first experiments, error-free wireless transmission of 1 Gb/s and 1.25 Gb/s for a wireless span of 2 m has been achieved. The maximum system’s data rate of 2.5 Gb/s is limited by the wireless receiver bandwidth. Wireless experiments were carried out in a lab environment up to 2.5 m span using a passive, i.e. amplifier-less W-band RoF wireless transmitter with an EIRP of 21 dBm. The passive RoF transmitter is composed of a high-power broadband InGaAs photodiode and a 21 dBi gain horn antenna.
