A circuit for frequency translating a radio frequency signal comprises a
plurality of mixer stages, each stage associated with a particular range
of frequencies of a radio frequency signal. The circuit further comprises
a switching circuit that communicates the radio frequency signal to a
selected one of the plurality of mixer stages in response to a control
signal. The selected mixer stage comprises a phase generation circuit
that generates a plurality of phase signals, and at least one mixer that
combines the radio frequency signal with one of the plurality of phase
signals to generate at least a portion of an intermediate frequency
signal.
