An integrated circuit radio transceiver and method therefor comprises circuitry that is operable to up-convert an outgoing continuous waveform signal to RF and that is further operable to down-convert and ingoing RF signal to one of a baseband or intermediate frequency in a manner that provides a linearized output current having an amplified current magnitude for mixing with a local oscillation in a mixer block. Specifically, a circuit portion is operable to produce a linearized current based upon an input signal. The linearized current is then produced to a current mirror block that produces a scaled and amplified output current. The scaled and amplified output current is then produced to a mixer block for mixing with a local oscillation to create the outgoing RF signal or the ingoing baseband or intermediate frequency signal.
