Abstract: A device including an optoelectric circuit that is configured to provide galvanic isolation between a first circuit and a second circuit is disclosed. The optoelectric circuit includes at least one non-inverting buffer and a metal semiconductor diode. The at least one non-inverting buffer is positioned between a collector of a phototransistor and an anode of a light emitting diode. The metal semiconductor diode is positioned between the collector of the phototransistor and the at least one non-inverting buffer.

Abstract: An antenna switching arrangement for a mobile device and a mobile device comprising the antenna switching arrangement. The arrangement comprises multiple radio frequency switches that are operably configured to couple either an internal antenna and/or an external antenna to a set of receivers and/or transmitters in the mobile device for indoor or outdoor operation.

Abstract: An electronic device is disclosed. According to at least one embodiment, the device includes a front-end module having at least one front-end connector, adapted to be connected to a cable adapted for receiving electrical signal, a reception module adapted to receive an electrical signal from the front-end connector, a back-end module configured to process an electrical signal, an interfacing module comprising at least an isolation module adapted to transmit, to the back-end module, an electrical signal received from the front-end module.

Abstract: The method of demodulation in an STB comprising a tuner including a local oscillator, a demodulator situated downstream of the tuner and a digital telephone base. In case of interference with the digital telephone base, the frequency of the local oscillator of the tuner is shifted by one or more synthesis intervals after scanning of an error indicator situated in the demodulator. This method makes it possible to insert a digital telephone base into an STB while circumventing disturbances in the operation of the STB when this base is transmitting.
