  6. 6. control method according to claim 5, it is characterised in that the control method is further comprising the steps of:
    3rd signalling channel and the 4th signalling channel are set, and gates the 3rd signal when receiving external control signal and leads to Road and the 4th signalling channel;
    By the second radiofrequency signal received while it is sent to the 3rd signalling channel and the 4th signalling channel;
    3rd signalling channel exports the 3rd frequency range radiofrequency signal in second radiofrequency signal, and isolates described second and penetrate The 4th frequency range radiofrequency signal in frequency signal;
    4th signalling channel exports the 4th frequency range radiofrequency signal in second radiofrequency signal, and isolates described second and penetrate The 3rd frequency range radiofrequency signal in frequency signal.
  7. 7. control method according to claim 6, it is characterised in that the 3rd signalling channel exports second radio frequency The step of the 3rd frequency range radiofrequency signal in signal is specially:
    The impedance for adjusting the 3rd matching network is the impedance for passing through the 3rd frequency range radiofrequency signal;
    4th signalling channel exports the step of the 4th frequency range radiofrequency signal in second radiofrequency signal and is specially:
    The impedance for adjusting the 4th matching network is the impedance for passing through the 4th frequency range radiofrequency signal.
