Specifically, immunity module 50 is worked as by receiving the carrier information that the modem 40 reports with real-time acquisition
It is preceding whether to carry out carrier aggregation, and the band information when carrying out carrier aggregation during acquisition carrier aggregation.
If the working frequency range of the main carrier component when immunity module 50 for obtaining carrier aggregation in real time, the default bar
Part includes：Main carrier component serves are in the first default frequency range.During carrier aggregation, the 40 real-time report carrier information of modem
The immunity module 50 is given, if the carrier information, which is shown, is currently carrying out carrier aggregation, and the main carrier component of carrier wave
The first default frequency range, such as B8 frequency ranges are operated in, then controls the first power amplifier 30a by the port inside change
Location so that the first path turns on, and alternate path is closed, and the signal of the transmitting path of carrier aggregation passes through first wave filter 70
Processing is filtered, to filter out low-frequency harmonics, transmitting/receiving front-end module 10 is then just sent to and is handled, finally passed through
Antenna 80 is launched.The working frequency range of carrier wave when carrier aggregation is unsatisfactory for the first preset condition or carrier aggregation terminates
When, then the first path is closed, opens alternate path.
If alternatively, the immunity module 50 for obtaining main carrier component and secondary carrier component during carrier aggregation in real time
Working frequency range, then the first preset condition include：Main carrier component serves are in the first default frequency range and the secondary carrier component work
Make in the second default frequency range.During carrier aggregation, which gives the immunity module 50, such as
The fruit carrier information, which is shown, is currently carrying out carrier aggregation, and the main carrier component serves of carrier wave preset frequency range first,
(such as main carrier component serves, in B8 frequency ranges, secondary carrier component serves are in B7 frequencies in the second default frequency range for secondary carrier component serves
Section or B3 frequency ranges), then the first power amplifier 30b is controlled by changing the port address inside register so that first
Path turns on, and alternate path is closed, and the signal of the transmitting path of carrier aggregation is filtered place by first wave filter 70
Reason, to filter out low-frequency harmonics, is then just sent to transmitting/receiving front-end module 10 and is handled, finally launched by antenna 80
Go out.
The present invention is used for the working frequency range for obtaining carrier wave in real time by the immunity module, in the working frequency range of the carrier wave
When meeting preset condition, control first power amplifier to close the first path and open alternate path, be unsatisfactory for described default
During condition, control first power amplifier to open the first path and close the alternate path, so that presetting work at this
Make frequency range and close the receiving channel of main carrier to avoid the harmonic wave of the receiving channel of the main carrier component to the hair of secondary carrier component
Harmonic wave interference when penetrating passage and produce interference, and then can reduce carrier aggregation.
