Abstract
A reconfigurable load modulation amplifier having a first power amplifier (PA) configured to be supplied by a first drain voltage and a second PA coupled in parallel with the first PA, wherein the second PA is configured to be supplied by a second drain voltage is disclosed. The reconfigurable load modulation amplifier includes a quadrature coupler configured to combine power from both the first PA and the second PA for output through an output port. Also included is control circuitry configured to set at least one of the first drain voltage and the second drain voltage such that the first drain voltage is different than the second drain voltage. In at least one embodiment, the control circuitry is further configured to dynamically adjust at least one of the first drain voltage and the second drain voltage such that the first drain voltage is different than the second drain voltage.
