Patent ID: 7714654

Claim:
A multi-mode radio frequency amplifier, comprising: a plurality of input transistors; a plurality of output branches each comprising a frequency selective load; and a switching stage interposed between said plurality of input transistors and said plurality of output branches for selectively coupling said plurality of input transistors to said plurality of output branches, said switching stage comprising a plurality of elements; where individual ones of operational modes of the multi-mode amplifier correspond to an individual one of said plurality of frequency selective loads, and where a particular one of said plurality of frequency selective loads is one of operating or non-operating during operation of said multi-mode amplifier; and where a gain of said multi-mode amplifier is reduced by controlling said plurality of elements to steer a predetermined portion of a total signal current, that is output from one of said input transistors, from an associated operating frequency selective load to a non-operating frequency selective load.
