Main-auxiliary field-effect transistor structures 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 gate bias network connected to the main path and to the auxiliary path, the main path and the auxiliary path each having different structures that are configured to improve linearity of the switching function.
