1. A method for switching an RF signal applied to a common port of a switch circuit from a first switch arm initially in an ON state to a second switch arm initially in an OFF state, the method including:
(a) setting the second switch arm to the ON state; and
(b) then setting the first switch arm to the OFF state;
wherein the first switch arm and the second switch arm each include a respective serial switch coupled between the common port and corresponding associated port, and one or more of the first switch arm and the second switch arm includes a respective shunt switch coupled to the corresponding associated port and configured to be coupled to a reference potential.
