Abstract: A radio frequency front-end includes a power amplifier. The radio frequency front-end also includes a coupler implemented in at least a portion of a matching circuit, the matching circuit coupled to an output of the power amplifier. The radio frequency front-end further includes a control loop comprising a first feedback terminal at an output of the power amplifier. The control loop includes the coupler coupled to the first feedback terminal of the power amplifier and is configured to generate a feedback signal provided to a second feedback terminal to adjust a gain of the power amplifier. The feedback signal is based on a reflected radio frequency signal provided by the coupler.

Abstract: A bond wire transformer comprises a plurality of primary bond wires coupled in parallel; and a plurality of secondary bond wires coupled in parallel, each secondary bond wire being spaced apart from and oriented relative to a corresponding primary bond wire so as to achieve a desired mutual inductance between the corresponding primary and secondary bond wires, thereby providing magnetic coupling between the primary and secondary bond wires.
