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.
