MLINC
Abstract
[0000] A multilevel linear amplifier with non-linear components, MLINC (1), for a radio frequency transmitter, the MLINC (1) comprising a first outphasing amplifier (2) adapted to receive a first set of input signals (S11, S12) and providing a first intermediate signal (S1) with a stepped envelope depending on a controlled portion (θc1) of a phase modulation in the first set of input signals (S11, S12); a second outphasing amplifier (3) adapted to receive a second set of input signals (S21, S22) and to provide a second intermediate signal (S2) with a stepped envelope depending on a controlled portion (0c2) of a phase modulation in the second set of input signals (S21, S22); and a combiner (6) adapted to combine the first and second intermediate signals (S2) into an output signal (Sout) having an envelope linearized due to a phase symmetry of the first and second intermediate signals (S1, S2).
