20100215123 | WIDEBAND DIGITALLY-CONTROLLED OSCILLATOR (DCO) AND DIGITAL BROADCASTING RECEIVER HAVING THE SAME - A wideband digitally-controlled oscillator (DCO) is provided. The wideband DCO includes an active element which is driven by a first digital control signal; a single inductor which is connected to the active element in parallel, and comprises fixed inductance; and a plurality of capacitors which are connected to the single inductor in parallel, and vary operating frequency by being selectively turned on or off by a second digital control signal. Accordingly, the wideband DCO capable of operating in a wideband frequency range using a single inductor is provided, and if the wideband DCO is implemented using a single integrated circuit (IC) chip, the size of chip is reduced as the single inductor is used. | 08-26-2010 |
20110136460 | MIXER AND RADIO FREQUENCY RECEIVER USING THE MIXER - A mixer used in a Radio Frequency (RF) receiver is provided. The mixer includes a first harmonic rejecter for rejecting a harmonic signal component from a first input signal; and a second harmonic rejecter for rejecting a harmonic signal component from a second input signal. The first harmonic rejecter and the second harmonic rejecter are connected in parallel to reject an image signal component from the first input signal and the second input signal. Thus, the RF receiver can reject the harmonic signal and the image signal without using an external element. | 06-09-2011 |
20130169342 | DEVICE AND METHOD FOR REMOVING HARMONIC COMPONENTS - An apparatus of a Harmonic Rejection Mixer (HRM) for removing a harmonic component and an operating method thereof are provided. The HRM includes a Local Oscillator (LO), at least one frequency converter, at least two mixers, at least one phase converter, and a combiner. The LO generates an LO signal. The at least one frequency converter multiplies the LO signal using different variables to provide the same to at least two mixers. The at least two mixers convert a frequency band of an input signal using the LO signal provided from the LO and the at least one frequency converter. The at least one phase converter controls a phase of an output signal of at least one other mixer excluding one of the at least two mixers. The combiner combines an output signal of the one mixer with an output signal of the at least one phase converter. | 07-04-2013 |
20140375513 | ANTENNA DEVICE AND DISPLAY APPARATUS HAVING THE SAME - An antenna device includes: a slot antenna unit configured to be positioned on a shield plate disposed in a rear side of a display; and a communication module configured to be connected to the slot antenna unit, to transmit and receive a signal to and from an external wireless device via the slot antenna unit. The slot antenna unit is exposed toward the display to radiate an antenna signal to the display. | 12-25-2014 |
20150070222 | SIGNAL TRANSFER APPARATUS HAVING ANTENNA UNIT - A signal transfer apparatus including an antenna unit is provided. A signal transfer apparatus includes a housing, an interface provided at a housing to be connected to an external device to transmit a signal to or receive a signal from the external device, an external case configured to cover the housing, an antenna unit configured to be a slot antenna, and a communication module which is connected to the slot antenna and transmits a signal to or receives a signal from an external wireless device through the slot antenna, a controller provided in the housing to be electrically connected to the interface and the antenna unit, and transmit an external signal received through the interface or the antenna unit directly to a display apparatus or convert the external signal and transmit the converted signal to the display apparatus. | 03-12-2015 |
20150351006 | NETWORK SYSTEM, ACCESS POINT, AND CONNECTION METHOD THEREOF - A network system, an access point, and a connection method thereof are provided. The access point includes a communicator configured to communicate with a wireless devices, and a controller configured to control the communicator to acquire authentication information based on a Uniform Resource Locator (URL) that is received from the wireless device, and to perform connection with an electronic device based on the acquired authentication information. | 12-03-2015 |
20150382194 | METHOD OF CONTROLLING ELECTRONIC DEVICE, ELECTRONIC DEVICE, METHOD OF CONTROLLING ACCESS POINT AND ACCESS POINT - An electronic device includes a network interface configured to communicate with an access point via a Local Area Network (LAN) cable, a wireless network interface configured to wirelessly communicate with the access point, and a controller configured to detect a connection to the access point via the LAN cable, control the network interface to receive access information for establishing a wireless connection with the access point from the access point, and control the wireless network interface to wirelessly connect to the access point using the received access information. | 12-31-2015 |
20160080314 | ACCESS POINT AND CONTROL METHOD THEREOF - Provided herein is an access point including a communicator configured to communicate with an external electronic apparatus; and a controller configured to, in response to determining that a preset first electronic apparatus is connected to the communicator, provide a signal for requesting connection between a second electronic apparatus connected to another access point and the first electronic apparatus to the another access point based on a type of an IP address (Internet Protocol) allocated to the access point, and form a single network with the another access point based on a signal in response to the connection request signal, thereby providing a user with convenience in communication connection with the electronic apparatus. | 03-17-2016 |
