Abstract

In this paper, a single-ended downconversion sub-harmonic mixer is implemented using 0.35-μm SiGe BiCMOS technology. Two lumped-element rat-races are applied to generate differential LO and RF signals. This single-ended rat-race mixer has the conversion gain of 25 dB and high port-to-port isolations at 10 GHz. The input return loss is about -10 dB and the compact chip size is 0.8 mm × 0.9 mm. The total current consumption is about 16 mA at 3.3 V.
