Abstract:
In an outphasing radio frequency (RF) transmitter, detecting differences of a first plurality of signal characteristics of a first plurality of amplified RF signals across at least a transmitter antenna or a plurality of load impedances, wherein the first plurality of amplified RF signals correspond to a first plurality of constant-envelope signals, and controlling generation of a second plurality of constant-envelope signals on a plurality of transmission paths. The second plurality of constant-envelope signals are generated based on the detected differences of the first plurality of signal characteristics. At least one of first calibrating or second calibrating, a second plurality of signal characteristics of the second plurality of constant-envelope signals. The first calibrating and the second calibrating are based on the controlled generation of the second plurality of constant-envelope signals.
