Abstract :
This paper presents the design, implementation and measurements of a C-band down-conversion active mixer. A Gilbert topology has been modified to provide RF power and noise matching, in order to improve the overall noise behavior. The circuit was fabricated in a 47 GHz BiCMOS process, achieving voltage conversion gain of 24 dB, double-side-band noise figure of 9.5 dB, P1dB and iIP3 of -11 dBm and -4 dBm, respectively. Current consumption is 4 mA from a 3 V supply.
