Abstract

See full text

Circuits and methods that enable stable and reliable “hot switching” from one antenna to another without turning RF power to the antennas OFF in wireless RF systems during at least some transmission events. One embodiment comprises an RF switch circuit including a common port configured to pass an RF signal, a plurality of switch arms each coupled to the common port and including an associated port, and a shunt termination impedance selectively couplable to the common port through a switch. Another embodiment comprises a method for switching an RF signal applied to a common port of a switch from a first switch arm initially in an ON state to a second switch arm initially in an OFF state, including: setting the second switch arm to the ON state, and then setting the first switch arm to the OFF state.
