摘要：In this paper a 3.5 GHz down conversion mixer with 20 MHz IF output signal for location-fixed WiMAX systems is presented. The proposed mixer is implemented with TSMC 0.18¦Ìm RF CMOS technology with 1.5V supply voltage which utilizes Current-Bleeding and Current-Reuse techniques to improve noise figure and conversion gain of conventional Gilbert-type structure. This mixer achieves 12 dB of conversion gain. For input power less than -36 dBm. The SSB and DSB noise figures are 6.5 dB and 3.5 dB, respectively. The proposed mixer achieved -15 dBm for P1dB and 11dB for IIP3 with power consumption of 10.12 mW.
