Abstract
The embodiments described herein provide wideband highly asymmetrical power efficient amplifier device that include a compact input power distribution network with input termination circuit. The input termination circuit is configured to provide control of the power distribution at the amplifier input. In one embodiment, the input termination circuit is configured to generate and reflect a frequency dependent portion of an input signal back toward the amplifier device inputs. This input reflection controls the input power distribution and shape of time domain input signal in a way that can affect amplifier device efficiency and linearity.
