Abstract
A wide dynamic range mixer which has a high linearity passive balun fabricated on a Si substrate for receiving an input RF signal and an active balun for receiving a local oscillator signal. The active balun includes high frequency, low voltage SiGe transistors to achieve low power amplification of the local oscillator signal. The output signals of the baluns are provided to a non-linear diode quad mixer device which provides a desired IF signal.
