An apparatus for providing a multi-mode interface between a baseband receiver and radio frequency (RF) circuitry. According to a preferred embodiment of the invention, the apparatus includes a first differential-to-single-ended converter, a second differential-to-single-ended converter and an analog-to-digital converter. The first differential-to-single-ended converter receives an incoming differential current pair to be converted into a first single-ended voltage signal. The second differential-to-single-ended converter receives an incoming differential voltage pair to be converted into a second single-ended voltage signal. Further, the analog-to-digital converter selectively receives an incoming single-ended voltage signal, the first single-ended voltage signal, or the second single-ended voltage signal to be converted into a digital signal to be further processed by the baseband processor. Note that the incoming single-ended voltage signal, as well as the incoming differential voltage and current signal pairs together form the multi-mode interface to the RF circuitry.
