Abstract:
1. A wireless handheld electronic wireless device comprising: storage that stores data; processing circuitry coupled to the storage that generates data for wireless transmission and that processes wirelessly received data; and wireless communications circuitry, wherein the wireless communications circuitry comprises: transceiver circuitry comprising a first transceiver circuit and a second transceiver circuit, wherein the first and second transceiver circuits communicate using different communications protocols and a common radio-frequency frequency band; an antenna that handles radio-frequency signals in the common radio-frequency frequency band; and a radio-frequency combiner and divider circuit comprising a first terminal coupled to the antenna, second and third terminals coupled respectively to the first transceiver circuit and the second transceiver circuit, a first path between the first terminal and the second terminal, wherein the first path has a first switch, a second path between the first terminal and the third terminal, wherein the second path has a second switch, and a third path between the second and third terminals, wherein the third path has a third switch that is operable in an open position that opens the third path and a closed position that closes the third path, wherein when the wireless communications circuitry is operated in a first mode the radio-frequency signals are simultaneously conveyed between the first terminal and both the second and third terminals over the first and second paths.
