A 2x6b 8GS/s 17-24GHz I/Q RF-DAC based Transmitter in 22nm FDSOI CMOS

We describe a 2 76 bit Cartesian RF IQ-modulator,\ua0implemented on 0.15mm2 in a 22nm FDSOI CMOS technology.\ua0Measurements show a 3dB bandwidth of 17–24 GHz and a\ua0saturated output power of 10.4dBm with a peak drain efficiency\ua0of 15.6%. The IQ-modulator has been verified up to 8GS/s. To\ua0the best of our knowledge, this is the highest-frequency CMOS\ua0RF IQ-modulator using sub-50%-duty-cycle LO signals, and the\ua0highest sample rate reported for >3 bit fully integrated Cartesian\ua0IQ-modulators
