Abstract

A dual-band filter and method thereof include a diplexer configured to process one of a first band signal and a second band signal, which includes a frequency band different from a frequency band of the first band signal, and block the other of the first band signal and the second band signal. A balun is configured to convert the first band signal from a differential signal to a single signal in response to the first band signal being transmitted, and convert the first band signal from a single signal to a differential signal in response to the first band signal being received. A direct current (DC) voltage supply port configured to supply a DC voltage to the balun when the first band signal is received.

Description

[0001] This application claims priority and benefit of Korean Patent Application No. 10-2014-0161690 filed on November 19, 2014 in the Korean Intellectual Property Office, the disclosure of which is hereby incorporated by reference. technical field [0002] The following description relates to a dual-band filter and its method of operation. Background technique [0003] With the development of wireless communication technology, the ability to operate within various wireless network communication standards has been realized in a single device. For example, in the case of Wi-Fi communication, the IEEE802.11ac wireless network standard has been added to the existing IEEE802.11a / b / g / n family. Devices capable of communicating using the 802.11ac standard can communicate using frequency bands of 20MHz, 40MHz, 80MHz, and 160MHz within the 5GHz frequency band. Therefore, dual-band technology supporting the existing 2.4GHz and added 5GHz bands has been used. [0004] Components that...
