Abstract
This disclosure relates to antenna switching circuitry and other radio frequency (RF) front-end circuitry. In one embodiment, the antenna switching circuitry includes a multiple throw solid-state transistor switch (MTSTS) and a multiple throw microelectromechanical switch (MTMEMS). The MTSTS is configured to selectively couple a first pole port to any one of a first set of throw ports and to selectively couple a second pole port to any one of a second set of throw ports. The MTMEMS is configured to selectively couple a third pole port to any one of a third set of throw ports. The third pole port of the MTMEMS is coupled to a first throw port in the first set of throw ports and a second throw port in the second set of throw ports of the MTSTS. Accordingly, the MTSTS is capable of routing multiple RF signals to and from the MTMEMS.
