摘要： The present invention relates to an antenna matching device that varies a frequency bandwidth according to mobile communication services, and to a transceiver having the same. To this end, an exemplary embodiment of the present invention provides a transceiver that varies a frequency band and a bandwidth according to required services in a mobile communication system, the transceiver including an antenna matching controller that generates a prescribed switch control signal according to a service requested by a user, an antenna variable matching unit that variably forms a matching circuit according to the switch control signal to be transmitted from the antenna matching controller and varies the frequency band and the bandwidth, an analog processing unit that processes a signal to be transmitted/received through the antenna variable matching unit, and a wideband antenna that transmits/receives a radio frequency according to the frequency band and the bandwidth set by the antenna variable matching unit. Another exemplary embodiment of the present invention provides an antenna matching device including a resistor that reduces a frequency bandwidth, an inductor that reduces a frequency passing band, a capacitor and a resistor that increase the frequency passing band, and switches that control the operations of the inductor and the capacitor. According to the present invention, unnecessary radiation power of a variable matching unit can be minimized, and maximum transmission power required according to services can be reduced. In addition, system construction costs can be reduced, and a user capacity can be increased.

摘要： The present invention relates to an RF repeater used in a time division method, and a method thereof. An RF repeater according to an exemplary embodiment of the present invention receives a downlink signal that is to be transmitted from a base station to a mobile terminal, performs first automatic gain control on the downlink signal, and extracts gain information from the downlink signal on which the first automatic gain control has been performed, on the basis of gain variation information that is the gain information for the downlink signal. Then, the RF repeater performs second automatic gain control on the downlink signal on the basis of the extracted gain information, and performs a control operation such that the downlink signal on which the second automatic gain control has been performed is transmitted to the mobile terminal. According to the exemplary embodiment of the present invention, the RF repeater maintains the received uplink signal at the predetermined level or more by using a pilot signal of a subcarrier that is not allocated during the downlink period, regardless of the number of mobile terminals that are connected to the RF repeater. As a result, the RF repeater can efficiently perform automatic gain control on the uplink signal without performing separate signal analysis or control.
