摘要:
This disclosure relates generally to radio frequency (RF) front-end circuitry for routing RF signals to and/or from one or more antennas. Exemplary RF front-end circuitry includes a multiple throw solid-state transistor switch (MTSTS) and a multiple throw microelectromechanical switch (MTMEMS). The MTSTS may be configured to selectively couple a first pole port to any one of a first set of throw ports. The MTMEMS is configured to selectively couple a second pole port to any one of a second set of throw ports. The second pole port of the MTMEMS is coupled to a first throw port in the first set of throw ports of the MTSTS. The MTSTS helps prevent hot switching in the MTMEMS since the first throw port of the MTSTS may be decoupled from the second pole port of the MTMEMS before decoupling the second pole port from a selectively coupled throw port of the MTMEMS.
