Abstract

The present invention provides a double-frequency band control circuit and a wireless device. The double-frequency band control circuit is applied to the wireless device and comprises an antenna. The double-frequency band control circuit further comprises a frequency band controller used for outputting first frequency band signals and second frequency band signals received by the antenna, a first frequency band control unit used for receiving the first frequency band signals outputted by the frequency band controller and outputting generated first frequency band signals to the frequency band controller, and a second frequency band control unit used for receiving the second frequency band signals outputted by the frequency band controller and outputting generated second frequency band signals to the frequency band controller, wherein the frequency band controller is further used for outputting the first frequency band signals outputted by the first frequency band control unit and the second frequency band signals outputted by the second frequency band control unit to the antenna. With the double-frequency band control circuit adopted, defects of complex internal setting of a wireless device and low antenna use cost which are caused by a situation that one antenna is correspondingly set for each frequency band, can be eliminated.

Description

technical field [0001] The invention relates to the technical field of communications, in particular to a dual-band control circuit and wireless equipment. Background technique [0002] Wireless Local Area Networks (WLAN). It is a very convenient data transmission system, which uses radio frequency (Radio Frequency, RF) technology, uses electromagnetic waves, replaces the local area network formed by the old twisted pair copper wire (Coaxial), and communicates in the air. The mobile terminal is connected to the wireless local area network through the wireless device. In order to meet the needs of a large number of mobile terminal access, the existing wireless device is equipped with dual frequency bands. Although the dual frequency band can meet the needs of accessing more wireless devices, the Each frequency band needs to be provided with an antenna correspondingly, which makes it more difficult to arrange the internal space inside the wireless device, and increases the co...
