ABSTRACT:
Aspects of a system for a power amplifier with an on-package matching transformer may include a DC/DC converter that enables generation of a bias voltage level within an IC die based on an amplitude of an input signal to a PA circuit within the IC die. The bias voltage level may be applied to a transformer, which is external to the IC die but internal to an IC package containing the IC die and/or a circuit board containing the IC package. One or more amplifier bias voltage levels, derived from the bias voltage level applied to the transformer, may be applied to the PA circuit.
