Active and Passive Electronic Components, 2002 In this paper a MMIC QPSK modulator is described. The bit rate of the baseband signal is 155 Mbits/sec, while the frequency of the carrier is fLO=10 GHz . The modulation is performed directly at the RF band and therefore an IF stage is not necessary. The
