Parallel main-auxiliary field-effect transistor configurations for radio frequency applications

Abstract:

Disclosed herein are switching or other active FET configurations that implement a main-auxiliary branch design. Such designs include a circuit assembly for performing a switching function that includes a branch including a main path in parallel with an auxiliary path. The circuit assembly also includes a first gate bias network connected to the main path. The circuit assembly also includes a second gate bias network connected to the auxiliary path, the second gate bias network configured to improve linearity of the switching function.
