Abstract
In this paper, a direct IQ modulator MMIC for high speed E-band wireless communication is presented. The IQ modulator consists of two balanced resistive mixer cells, on-chip marchand balun and two Lange couplers for quadrature LO signal generation. When operating as a single side band mixer, it shows conversion loss of 11 dB and side-band suppression higher than 20 dB. LO to RF isolation has been measured to be more than 30 dB.
