Band transmissions signal) in running order such as downloading data, and the mobile communication equipment 100 pass through B41 frequency ranges with it is external
Equipment carries out voice communication (i.e. the B41 frequency ranges of mobile communication equipment 100 and WIFI frequency ranges coexist), minimum due to B41 frequency ranges
The highest frequency of frequency and WIFI frequency ranges is very close, if the B41 frequency ranges is still made to be provided with low-pass filter 101 at this time
Signal is transmitted on first sub-channel 10311, by it will cause larger interference, leads to the performance of B41 frequency ranges and/or WIFI frequency ranges
Poor performance.
Therefore, because low-pass filter 101 is very poor to the inhibition of WIFI frequency ranges, so in the first radio frequency band such as B41
In the case that frequency range and WIFI frequency ranges coexist, it can be gated by the switch 105 of the embodiment of the present disclosure and be provided with bandpass filtering

It crosses, while other frequency ranges such as WIFI frequency ranges is inhibited to pass through.So it is the first radio frequency in the working frequency range of mobile communication equipment 100
When frequency range such as B41 frequency ranges and in running order WIFI chips 107, communication chip 104 can control first radio frequency band
Such as B41 frequency ranges are emitted by radio-frequency antenna 102 on the second sub-channel 10312 and/or receive signal, to reduce interference.
