Abstract

A new mixer topology is proposed which combines in parallel two single-balanced mixers, one Gilbert mixer and the other a so-called transconductance mixer. Such a mixer is supposed to improve linearity performance without degradation in noise figure and conversion gain. Based on the proposed topology, an active mixer operating at 23 GHz has been designed and fabricated in InGaP/GaAs technology. Under a power consumption of 52.6 mW, the measured IIP3 is +12 dBm, with 4 dB conversion gain and 11.5 dB double sideband noise figure.
