In this work, a new mixer topology operating with second harmonically pumped mixing technique is proposed. The proposed topology is developed to be used in zero-if mixers. Analysis are performed and the appropriate operation conditions for second harmonically pumped mixing are investigated for the topology which is suitable for functioning in a wide band. SiGe technology is used for the realization of the circuit. Schematic simulations are performed and according to the simulation results, within 1-12GHz range, 20dB of conversion voltage gain and a noise figure less than 14dB is obtained.
