In this paper, the feasibility of transmitting and receiving complex modulated data signals with different modulation formats in a superheterodyne system setup, using a 220 GHz wireless link based on millimeter-wave monolithic integrated circuits (MMIC), is shown. It was possible to transmit an 8PSK modulated signal over a distance of 2.8 m with an error vector magnitude (EVM) of 10.7%, resulting in a bit error rate of 10^-6. A 16QAM and a 16APSK signal could be transmitted with a resulting EVM of 10.5% and 9.7%, respectively.
