Abstract: A wireless multimode radio access technology (RAT) handheld device (100) utilizes first and second wireless radio access technology receivers (108 and 110) includes at least one shared receiver component (120 or 121 or 123) that is within a shared receive path that is shared by both the different RAT receivers (108 and 110) when in a multimode receiver operation. The handheld device (100) includes a radio access technology bypass switch (106) and corresponding logic (112), that controls the RAT bypass switch to bypass the at least one receiver component (120 or 121 or 123) that is shared between the first and second RAT receivers (108 and 110), when the handheld device is in a single RAT receive mode of operation. A method is also disclosed that includes determining (202) if a single RAT receive mode of operation or a multi-RAT receive mode of operation is desired.

Abstract: Disclosed are communication devices that combine at least two antenna paths to a single RF connector having a single probe port for testing and connecting accessories. Prior to insertion of a probe, the transceivers are coupled to their respective antennas. When the probe is inserted into the probe port, the connector is activated, so that both transceivers send signals to and receive signals from the single probe port. Also disclosed is a method for testing an electronic device. The method includes powering up the plurality of transceivers, and engaging the probe port with a probe so as to perform testing. Engaging the probe port with the probe decouples the plurality of transceivers from the plurality of antennas and couples the plurality of transceivers through respective diplexing networks to the probe part.

Abstract: A mobile communication device that includes an antenna configured to send and/or receive a first signal in a first frequency band and a second signal in a second frequency band, first receiver circuitry configured to receive signals in the first frequency band, a switch having a first position, and a first diplexing network coupled to the antenna, the first diplexing network also coupled to the switch, and first diplexing network also coupled to the first receiver circuitry. The first diplexing network can be configured to pass signals in the first frequency band to the first receiver circuitry and to block signals in the second frequency band from the first receiver circuitry. The first diplexing network can also be configured to pass signals in the second frequency band to the switch. The mobile communication device can also include a second diplexing network coupled to the switch at the first position, the second diplexing network corresponding to the second frequency band.
