Described 3rd signalling channel exports the 3rd frequency range radiofrequency signal in described second radiofrequency signal, and isolates the 4th frequency range radiofrequency signal in described second radiofrequency signal;
Described 4th signalling channel exports the 4th frequency range radiofrequency signal in described second radiofrequency signal, and isolates the 3rd frequency range radiofrequency signal in described second radiofrequency signal.
10. control method according to claim 9, is characterized in that, the step of the 3rd frequency range radiofrequency signal that described 3rd signalling channel exports in described second radiofrequency signal is specially:
The impedance of described 3rd matching network is regulated to be the impedance that described 3rd frequency range radiofrequency signal is passed through;
The step of the 4th frequency range radiofrequency signal that described 4th signalling channel exports in described second radiofrequency signal is specially:
The impedance of described 4th matching network is regulated to be the impedance that described 4th frequency range radiofrequency signal is passed through.
