Abstract
An improved balanced mixer is provided for use in radio communication devices. The improved balanced mixer comprises a known Gilbert type mixer, a transconductance amplifier, a signal splitter, and a dual feedback structure from the pre-amplifier output to the input ports, thereby providing better linearity, that is, better input third order intercept point (IIP3), and improved impedance matching, without increasing the circuit noise figure.
