Abstract

In this paper we present a monolithically integrated image-rejection resistive mixer that shifts a signal in the 1 - 2 GHz band up to the 14 - 15 GHz band using a 16 GHz local oscillator (LO). The circuit was realized with our 0.2 /spl mu/m InP HEMT in-house process using a coplanar-waveguide technology. The fabricated circuit presents a peak conversion gain of -7.3 dBm for 2 dBm LO power, an LO suppression of 20 dB and an upper-sideband rejection of more than 17 dB. This performance is excellent if compared to the best reported results for InP HEMT resistive mixers.
