An MMIC mixer with HEMTs in a Gilbert cell configuration is proposed. Active devices are biased in the subthreshold region where current dependence on the drain-to-source voltage is nearly linear. Both input and output active baluns are included in the design to reduce the LO level. The chip was fabricated using GaAs HEMTs with the ED02AH process of the Philips Microwave Limeil foundry. Measurements show a good performance from 0.3 to 7 GHz, with gain in a 7 GHz bandwidth.
