Abstract

The split-gate technique allows multi-finger RF devices to have electrically reconfigurable peripheries which can be used to actively change output power while maintaining high-efficiency. Previous work has demonstrated the theoretical concepts using the simplest possible test cell, this work expands the concept using four independent gates which allows a more desirable range of achievable output powers.
