Patent ID: 8594233

Claim:
A communications device comprising: a plurality of In-phase (I) power amplifiers configured to generate a plurality of I amplified signals; a plurality of Quadrature (Q) power amplifiers configured to generate a plurality of Q amplified signals; a first phase shifter coupled upstream of said plurality of I power amplifiers; a second phase shifter coupled upstream of said plurality of Q power amplifiers; an I controller coupled to said plurality of I power amplifiers and configured to selectively enable at least one of said plurality of I power amplifiers based upon at least a selected output power and to control said plurality of I power amplifiers to modulate and mix an I carrier signal directly received from said first phase shifter with an I digital baseband signal to generate the plurality of I amplified signals; a Q controller coupled to said plurality of Q power amplifiers and configured to selectively enable at least one of said plurality of Q power amplifiers based upon at least a selected output power and to control said plurality of Q power amplifiers to modulate and mix a Q carrier signal directly received from said second phase shifter with a Q digital baseband signal to generate the plurality of Q amplified signals; a power combiner configured to combine the plurality of I amplified signals and the plurality of Q amplified signals in a combined amplified signal; and an antenna coupled to said power combiner.
