Abstract :
This paper proposed a dual-mode down-conversion mixer for 3.1-10.6 GHz UWB and 2-11 GHz WiMAX systems. A full integrated 20 MHz IF with active output balun is designed for the mixer. The simulated conversion gains are 15.7 dB to 16.6 dB and 14.5 dB to 14.3 dB for UWB and WiMAX, respectively. Based on the TSMC 0.18 mum CMOS RF technology, the simulated IIP3 are -4.419 dB and 4.915 dB, for UWB and WiMAX, respectively. Both consume 10.2 mA of current from a 1.8 V supply.
