N2 - This paper describes simulation results of high dynamic range mixer, based on resistive ring topology. Mixer is designed using TSMC CMOS 0.18um technology. This mixer downconverts RF signals in the range 2-6 GHz to low IF using LO signals below corresponding RF frequencies and perform low-pass filtering with 3dB bandwidth 33 MHz. Unlike pure resistive ring topology, mixer has a positive power gain. Output 2nd and 3rd order intercept point for proposed mixer is 41dBm and 22dBm, resulting in dynamic range over 60dB even for high-throughput transceivers. Mixer have an integrated LO drive with gain 6dB, so does not require significant LO power to operate. The mixer has DC power consumption 54mW and can be used in the most demanding ultra-wideband OFDM radio and WLAN communication systems.
