Abstract
This disclosure relates to radio frequency (RF) front-end circuitry. In one embodiment, the RF front-end circuitry is arranged to provide antenna switching functionality for a Worldphone or a World tablet. The RF front-end circuitry may include front-end switching circuitry, a multiple throw microelectromechanical switch (MTMEMS), a first antenna port, a second antenna port, and a third antenna port. The front-end switching circuitry of the RF front-end circuitry is configured to selectively couple one or more RF ports to either the first antenna port or the second antenna port. The MTMEMS is configured to selectively couple a pole port coupled to the third antenna port to any one of a set of throw ports, which may be RF ports or may be coupled to RF ports. As such, the RF front-end circuitry is capable of providing antenna switching functionality between three antennas for a Worldphone or World tablet.
