Abstract :
This paper presents a high conversion gain folded mixer for a 2~11 GHz WiMAX system with 20 MHz IF output signal. The simulated conversion gain is ranged from 18.9 to 21.5 dB for the full bandwidth. The simulated NF is 13.5 to 17.6 dB with 0.2 to 4.4 dBm IIP3. The folded mixer is designed and fabricated in TSMC 0.18 mum RF CMOS technology with 1.8 V VDD and 1.5 V VRF supply voltage. The DC power consumption of the folded mixer core is 11.8 mW.
