Long range millimeter wave wireless links enabled by traveling wave tubes and resonant tunnelling diodes

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).
