摘要

A Broadband Gilbert Down-Converter with step-impedance rat-race coupler is demonstrated using 0.13 μm standard CMOS technology. The proposed method utilizes higher effective dielectric-constant, phase-inverter and step-impedance techniques simultaneously to make the rat-race coupler more compact (- 64% reduction) and phase-balanced over a wide operating bandwidth. The down-converter has NF of 16 dB and LO-to-RF isolation of better than 35 dB. The mixer core consumes 2.9 mA at Vdd=1.8 V.
