Abstract

One embodiment of the present invention relates to a dual mode receiver that includes an RF splitter configured to operate in two modes, wherein in a first mode a single low noise amplifier is active to receive an RF input signal, and in a second mode two low noise amplifiers are active to receive the RF input signal. The receiver further includes a programmable degeneration component operably coupled to the RF splitter, and configured to provide a first performance characteristic in the first mode, and a second, different performance characteristic in the second mode, wherein the first and second performance characteristics influence an input impedance of the RF splitter to be substantially the same in the first and second modes.
