    摘要： A mobile wireless communications device includes a portable housing having a metallic front housing forming a peripheral sidewall as a metallic ring. A circuit board is carried by the portable housing and forms a chassis ground plane. A wireless communications circuit is carried by a circuit board. An antenna circuit is carried by a circuit board and connected to the wireless communications circuit. A frequency selective grounding circuit is positioned at a selected grounding location at the chassis ground plane and metallic front housing and forms a harmonic trap that responds to a specific range of frequencies.

    摘要： A circuit for reading and programming a fuse. The electronic circuit includes a data fuse coupled to a data node and a reference fuse coupled to a reference node. A programming circuit is coupled to the data node, wherein the programming circuit is configured to, when activated, cause the data fuse to be programmed. A sensing circuit is configured to draw current from the data node and the reference node in order to develop a voltage differential between the data node and the reference node during a read operation. A read circuit is configured to, when activated, enable the sensing circuit to develop the voltage differential during the read operation. A protection circuit is configured to form a voltage divider within the sensing circuit during programming of the fuse.

    摘要： A mobile wireless communications device has a portable handheld housing. A circuit board is carried by the portable handheld housing. RF circuitry is carried by the circuit board. A diversity antenna and main antenna are carried by the portable handheld housing and coupled to the RF circuitry and operative together. The RF circuitry tunes the diversity antenna into a diversity communications frequency band to achieve a diversity mode of operation with the main antenna and tunes the diversity antenna into a non-diversity communications frequency band when cross-coupling has occurred from the diversity antenna to the main antenna when operating in the diversity communications frequency band. A switch is carried by the portable handheld housing and connected to the RF circuitry and coupled between the diversity and main antennae and disconnects the diversity antenna when operating in the non-diversity band to prevent cross-coupling from the diversity antenna to the main antenna.
