Abstract

The invention discloses a WIFI circuit capable of improving filtering performance and a method thereof. The circuit comprises a wireless transceiver, a power amplifier, a lowpass filter, a transceiving switcher, a low-noise amplifier and an antenna. An adjustable bandpass filter is respectively arranged between the wireless transceiver and the power amplifier, and between the transceiving switcher and the low-noise amplifier. The control end of the adjustable bandpass filter is connected with the wireless transceiver, so that a signal filtering bandpass range is changed to adapt to a bandwidth range of a current signal, under the control of the wireless transceiver. According to the circuit and the method, the wireless transceiving out-of-band interference can be reduced, and the communication quality and speed of the wireless WIFI can be improved.

Description

technical field [0001] The invention relates to the field of wireless technology, in particular to a WIFI circuit capable of improving filtering performance and a method thereof.
