Abstract

Improved linearity performance for radio-frequency (RF) switches. In some embodiments, a switching device can include a first terminal and a second terminal, and a plurality of switching elements connected in series to form a stack between the first terminal and the second terminal. The switching elements can have a non-uniform distribution of a parameter that results in the stack having a first linearity performance that is better than a second linearity performance corresponding to a similar stack having a substantially uniform distribution of the parameter.
