The paper presents the transmission of QPSK and 8-PSK modulated signals over a distance of 40 m as well as a characterization of the RF frontend based on S-parameter measurements and back-to-back signal transmission. The link quality is evaluated in terms of error vector magnitude (EVM) measurement. For a symbol rate of 10 GBd, the EVM measurement shows values of 10:3 % and 15:2 % for the QPSK and 8-PSK signal, respectively.enMMICsMillimeter wave circuitsmillimeter wave communicationradio linkwireless communicationdata transmissioncomplex modulated data signals667conference paper
