A system-on-package analog synchronous QPSK demodulator for ultra-high rate 60 GHz wireless communications

Summary form only given, as follows. A highly efficient QPSK demodulator module is presented, which synchronizes carrier phase and frequency in the analog domain. By this, the need for high-precision ADCs is eliminated, which become especially problematic for data rates exceeding several Gbit/s. Within the work, synchronous demodulation of up to 5 Gbit/s data rate is demonstrated. Moreover, it is experimentally validated that through the presented receiver concept a substantial amount of phase noise suppression can be achieved.
