20-Gbit/s ASK wireless system in 300-GHz-band and front-ends with InP MMICs

We present a 20-Gbit/s ASK wireless system in the 300-GHz band for kiosk data downloading. The front-ends (transmitter and receiver) are manufactured by using InP-based monolithic microwave integrated circuits with high electron mobility transistors. We successfully demonstrate 20-Gbit/s data transmission using these front-ends at link distances from 50 cm to 1 m. The measured bit error rate is less than 10

up to the distance of 1 m.
