Abstract :
A 16-46 GHz mixer using broadband balun fabricated in standard 0.18-mum CMOS process is demonstrated. The broadside-coupled balun with wide bandwidth and low insertion loss utilizes the inherent 3D multilayer structure in CMOS process. The mixer exhibits radio frequency bandwidth from 16 to 46 GHz with a conversion loss ranging from 13 plusmn 1.5 dB, and achieves bandwidth over 103% with a compact chip size of 0.24 mm2.
