This paper presents a 135 GHz direct-digital modulation 16-QAM transmitter employing a Cartesian architecture with separate phase and amplitude modulation. The transmitter, implemented in 28 nm CMOS, demonstrates a peak output power of 0 dBm. A maximum data rate of 32 Gb/ <tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">$s$</tex> is achieved using 16-QAM without any equalization or pulse shaping. Star-QAM and QPSK modulations lead to data rates of 27 Gb/ <tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">$s$</tex> and 24 Gb/ <tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">$s$</tex> , respectively. The transmitter consumes 130 mW of DC power.
