An apparatus and method for providing an LTE service in an electronic device. The method includes: transmitting or receiving a voice signal through a first antenna and a data signal through a second antenna when the electronic device provides a multi-communication service. At least one switch connects at least one antenna and at least one communication interface with each other. When the electronic device provides a single communication service, transmitting or receiving a data signal or a voice signal through the first antenna, using the at least one switch.

Method for providing communication service and electronic device thereof

A circuit device for preventing radiation emission in a portable terminal with two cameras is provided. The device includes a first camera, a second camera, a processor, and a 3-state buffer. The processor outputs a first control signal controlling an operation of the first camera and a second control signal controlling an operation of the second camera. The 3-state buffer electrically connects between the first camera and the processor, and connects or disconnects between the first camera and the processor depending on the first control signal.

Circuit device for preventing radiation emission in portable terminal with two cameras

An apparatus for controlling power consumption in a Personal Digital Assistant (PDA) phone is provided. The apparatus includes a PDA controller for applying a first signal or a second signal to a PDA voltage module, for sensing a voltage of a first capacitor changed according to the first or second signal, and for operating at the voltage of the first capacitor, and the PDA voltage module in which a first resistor is in a shorted or open condition according to the first or second signal, and a voltage applied to the first capacitor is changed according to the shorted or open condition of the first resistor.

Apparatus for controlling power consumption in PDA phone

Provided is a method for protecting user data in a PDA telephone having functions of a PDA and a telephone. The method includes checking a voltage of the PDA telephone through a first low voltage sensor when both the PDA and the telephone are in OFF states and prohibiting user's manipulation on the PDA telephone when the voltage of the PDA telephone goes to a first low voltage.
