An electronic device includes two cameras each with a light sensor. The electronic device uses the light sensor of one of the two cameras which is operational to detect an ambient luminance, and determines if the detected ambient luminance is less than a preset shading value. In response to the detected ambient luminance being less than the preset shading value, the electronic device interchanges the cameras to work. That is, the electronic device powers down the one of the two cameras which is operational and activating the other one of the two cameras.

Electronic device and method of camera control

A printed circuit board (PCB) antenna includes an antenna matching network, an antenna body, and a high frequency (HF) connector. The antenna matching network is used to electrically connect to a signal processing circuit. The antenna body is connected to the antenna matching network, the antenna body includes a bared area, the bared area is used to electrically connect to a conductive object and then to be grounded when the signal processing circuit is needed to be tested. The high frequency (HF) connector is electrically connected to the antenna body and is used to connect to a test device when the signal processing circuit is needed to be tested.

Printed circuit board antenna, printed circuit board, and electronic device

A three-pole three-throw switch and a communication device employing the three-pole three-throw switch includes six diodes and six inductors. The six diodes are connected in series with a same direction. Common nodes of each two diodes form three poles and three throws. The three poles and the three throws are linked together in circular form. The three poles and the three throws receive control signals via the six inductor, respectively.

Three-pole three-throw switch and communication device

A radio frequency (RF)-based communication terminal includes a first switching chip, a second switching chip, a comparison module, a low noise amplifier (LNA), a first filter, a power amplifier (PA), a second filter, and a control module. The comparison module compares the power of a radio signal Rx received from a base station with a pre-stored signal and to output a control signal according to the comparison result. The control module controls conductive modes of the first and the second switching chips according to the control signal. In the first conductive mode, a radio signal Tx is sent out from the PA and the second filter. In the second conductive mode, the radio signal Tx is exchanged to send out from the LNA and first filter.

Radio frequency-based communication terminal having two exchangeable transmitting paths

A wireless communication device includes an antenna module, a transceiving module, and a switch module. The antenna module includes a first antenna and a second antenna. The transceiving module includes a first transceiver and a second transceiver. The switch module switches different connections between the antenna module and the transceiving module, and includes a first single-pole-double-throw (SPDT) switch, a second SPDT switch, a third SPDT switch, a first duplexer, a second duplexer, and a double-pole-double-throw (DPDT) switch.
