摘要： A resonant switch with a first port and a second port has a capacitor connected thereto. A triple inductor network has a center inductor connected to the first port and the second port, and first and second peripheral inductors each electromagnetically coupled thereto. In a deactivated state, the center inductor and the capacitor define a parallel resonance at a predefined operating frequency range, and in an activated state, insertion loss associated with the center inductor is substantially minimized to metallic trace loss attributable thereto.

摘要： A mobile terminal apparatus includes: a microphone; a switch control unit, which switches between a normal mode, in which a voice uttered toward the microphone is transmitted to an intended party, and a mute mode, in which the voice is not transmitted to the intended party; and a proximity sensor, which detects whether a detection object is in proximity to the proximity sensor, wherein, while the mute mode is being executed, if the detection object is detected by the proximity sensor, the switch control unit switches to the normal mode.

摘要： Exemplary embodiments include an antenna for receiving electromagnetic radiation in a broadcast radiation band and a near-field radiation band to generate a Radio Frequency (RF) signal. A coupling element couples the RF signal to a first port and at least one additional port, which may be a second port and a third port. A wireless power receiver on the first port includes a rectifier for converting the RF signal to a DC signal when the antenna couples to radiation in the near-field radiation band in a coupling-mode region of the antenna. A near-field communication transceiver includes circuitry for communicating information on the antenna in the near-field radiation band when the coupling element couples the second port to the RF signal. A broadcast receiver on the third port includes circuitry for receiving and tuning the broadcast radiation band when the coupling element couples the third port to the RF signal.
