MMIC based wireless data transmission of a 12.5 Gbit/s signal using a 220 GHz carrier

In this paper wireless data transmission at 220 GHz with up to 12.5 Gbit/s data rate and over a distance of 2 meters is presented. At 12.5 Gbit/s, the measured eye diagram quality factor is 3.59. At 10 Gbit/s, the 2¹⁵ - 1 PRBS signal is received with a measured bit error rate better than 3.0 · 10^-10. The signal is modulated onto a carrier frequency at 220 GHz using fully integrated 50 nm metamorphic HEMT-based transmit and receive MMICs, packaged into waveguide modules. Horn antennas with attached lenses are used to collimate the beam.
