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.
