Abstract
Embodiments of radio frequency (RF) systems include a power amplifier having a primary winding and a secondary winding. The primary winding can be biased in different states in transmit and receive modes such that a difference between center frequencies of the primary winding and the secondary winding are significantly different in the different modes.
