Abstract
A digitally configurable transformer that performs switched transformer combining is disclosed. The flexible transformer includes switches that are dynamically configurable to efficiently combine RF power from power amplifier cores to achieve different power levels. The disclosed transformer is efficient at a broad range of power levels, leading to high power output efficiency. The transformer may be part of any power amplifier design that uses the transformer for power combining.
