  • Publication number: 20100087146
    Abstract: A method and device for performing short range wireless communication of a mobile terminal reduces a time period of searching for terminals for connection. A short wireless communication distance can be extended by switching to/from a directional antenna and an omni-directional antenna of the mobile terminal according to a user setting. The method of performing short range wireless communication in a mobile terminal including a directional first antenna, an omni-directional second antenna, and a switch unit for switching the first antenna and the second antenna includes: activating the first antenna and searching for connectable terminals, when a short range wireless communication function is activated; and forming a communication channel with the found terminal, if a connectable terminal is found after activating the first antenna.

  • Publication number: 20040185924
    Abstract: The present invention relates to a folder-type portable radiotelephone having a main body including a printed circuit board, and a subbody including an LCD (Liquid Crystal Display) module. The subbody is connected to the main body in such a way that the subbody can be folded and unfolded by a hinge device. The radiotelephone comprises at least one connection device mounted on a portion where the main body meets with the subbody. The connection device electrically connects a grounding portion of the printed circuit board included in the main body to a grounding portion of the LCD module included in the subbody when the radiotelephone is folded and unfolded. Consequently, current density radiated from an antenna device is reduced, contributing to a remarkable reduction in SAR (Specific Absorption Rate).

  • Patent number: 6496072
    Abstract: An amplifying apparatus for a mobile station receiver is disclosed. A low-noise amplifier amplifies a received signal to a preset level. A controller detects a level of a signal corresponding to a first frame of the received signal output from the low-noise amplifier, and generates a control voltage according to the detected level. An attenuation determining resistor determines an attenuation of the received signal. A first switching element is connected in series to the attenuation determining resistor, and is turned ON according to the control voltage so as to attenuate the received signal through the attenuation determining resistor. An impedance compensation resistor is connected in parallel to the attenuation determining resistor, and compensates for a decrease in an impedance due to turn-ON of the first switching element. Further, a second switching element is connected in parallel to the impedance compensation resistor and the first switching element.
