This paper describes a new project to realize a high data rate point to point wireless system above 150 GHz. The upper end of the D-band spectrum is used (151-174 GHz) for full duplex transmission. The aims it to enable a full fiber on air with more than 1 km range to provide up to 45 Gb/s data rate. The system consists in a transmitter using a directly modulated Resonant Tunnelling Diode (RTD) oscillator and powered by novel traveling wave tubes (TWT).
A novel front end for high data rate point to point links at D-band (151 -174.8 GHz) will provide up to 45 Gb/s over 1 km range. The low power signal generation is provided by a low cost Resonant Tunnelling Diode (RTD) oscillator. The RTD oscillator is connected to a Traveling Wave Tube that provides up to 10 W transmission power.
