ABSTRACT:
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.
