Specifically, reflected signal can be obtained using circulator when realizing step 803 and step 804, and a conjunction is carried out to the reflected signal, the second coupled signal is obtained.So, the isolation of first coupled signal and second coupled signal can be increased, the directionality of the signal of output is improved, so as to reduce the interference that first coupled signal is caused to second coupled signal.
Further, second coupled signal is carried out time delay processing by this, obtains the second coupled signal of delay, including：Time delay processing is carried out to second coupled signal using FBAR, BAW or SAW technology,
Obtain the second coupled signal of the delay.
