A single-ended wideband downconversion Gilbert micromixer is demonstrated in this paper using 0.35-um SiGe BiCMOS technology. Because of the wideband matching property of the micromixer, it can perform broad frequency translation. The TIA is utilized in the IF stage while a broadband Marchand balun is employed not only to generate differential LO signals but also to reserve the wideband operation of the mixer. This single-ended wideband mixer has the conversion gain of 15 dB, IP1dB of-17 dBm, and HP3 of -6.5 dBm and works from 3.5 to 14.5 GHz. The input return loss is below -14 dB and the chip size is 1×1 mm2.
