A mixer device is disclosed, which is fabricated as a bipolar-complementary metal oxide semiconductor (BiCMOS) integrated circuit device, to provide improved linearity and dynamic range, at higher operating frequencies. A mixer device configured according to an embodiment includes a driver circuit comprising bipolar junction transistors (BJTs) to convert a local oscillator signal to a high slew-rate gate drive signal. The driver circuit is configured as a quasi-complementary driver employing NPN BJTs. The mixer device further includes a mixer circuit comprising CMOS field-effect transistors (FETs) configured to mix an input signal with the gate drive signal to generate an output signal through the application of the gate drive signal to the gate port of the CMOS FETs. The mixer device further includes a voltage biasing circuit to provide a biased body voltage to the FETs to allow overdriving to a negative voltage relative to the body voltage.
