Abstract:
A wireless device is disclosed. The wireless device of the present invention is characterised by comprising: an antenna transmitting and receiving data via a first frequency band having a first transmission frequency band and a first reception frequency band, and a second frequency band having a second transmission frequency band and a second reception frequency band, wherein at least a part of the first transmission frequency band overlaps with the second reception frequency band; a plurality of band-pass filters including a first band-pass filter corresponding to the first transmission frequency band and the second reception frequency band; and switches including a first switch for separating the path of the first transmission frequency band and the second reception frequency band on a signal path with respect to the first band-pass filter of the plurality of band-pass filters. According to the present invention, carrier aggregation of first and third paths and carrier aggregation of second and fourth paths can simultaneously occur using a single quadplexer, and thereby an antenna can be used without dividing and the cost for a quadplexer can be saved.
