摘要： A mobile wireless communications device may include a housing, a wireless receiver carried by the housing and configured to receive communication signals over a wireless frequency range, a wireline transmitter carried by the housing and configured to transmit communication signals overlapping in frequency with the wireless frequency range, and a controller carried by the housing and coupled with the wireless receiver and the wireline transmitter. The controller may be configured to determine when the wireless receiver is to begin receiving and, based thereon, switch the wireline transmitter to a suspended communication mode during which transmission is disabled. The controller may also be configured to determine when the wireless receiver has completed receiving and, based thereon, switch the wireline transmitter to a normal communication mode in which transmission is enabled.

In one aspect, the mobile electronic device comprises a chassis including a ground plane; a processor carried by the chassis; a frequency tunable antenna carried by the chassis and fed by an inductor; a communications interface carried by the chassis and operative with the processor for receiving and transmitting RF signals via the frequency tunable antenna; audio circuitry carried by the chassis and operative with the communications interface and processor; an audio transducer having a coil in proximity to the frequency tunable antenna for at least one of receiving and transmitting audio signals from and to the audio circuitry; and at least one RF choke configured for blocking RF energy from the frequency tunable antenna through the audio transducer to the ground plane and decoupling the antenna from the audio transducer to minimize any detuning of antenna impedance match and degradation in antenna gain. At least one tunable capacitor is connected in parallel with at least one of the audio transducer coil, the RF choke and the inductor, for providing dynamic RF energy blocking over an operating frequency range of the frequency tunable antenna.
