Multi-gigabit data transmission using MMIC-based E-band frontends

In this paper, the transmission of broadband complex modulated signals with data rates up to 48 Gbit=s using an E-band MMIC-based analog frontend is shown. The paper presents the transmission of QPSK, 8-PSK and 16-QAM modulated signals with a symbol rate of 12 GBd. The received signal quality is evaluated in terms of error vector magnitude, which, measured in a coherent setup, shows values of −18.8 dB, −18.7 dB and −20.9 dB for the QPSK, 8-PSK and 16-QAM signal, respectively. Using a more application oriented incoherent setup, the signal quality decreases about 1 dB.
