Abstract :
In this study, the authors introduce a zero-IF sub-harmonic mixer with high isolation in the 5GHz band using 0.18μm CMOS technology. Placing an LC-tank between the class AB stage and the mixer core improves the isolation between the LO and RF ports. The measured isolation is obtained with a 48 dB between LO and RF ports; and a 9.5dB conversion gain is acquired while consuming 7mA at 2.5V supply voltage
