ABSTRACT:
A multi-band band pass filter, including: first and second multi-order asynchronous resonators connected to each other by a coupling resonator and connected to respective first and second matching resonators, the first matching resonator connected to a signal-in terminal and second matching resonator connected to a signal-out terminal respectively; a first reference resonator connected between the signal-in terminal and a reference-in terminal and a second reference resonator connected between the signal-out terminal and a reference-out terminal, the first multi-order asynchronous resonator connected between the first matching resonator and the coupling resonator to the first reference terminal and the second multi-order asynchronous resonator connected between the second matching resonator and the coupling resonator to the reference-out terminal, the reference-in terminal connected to the reference-out terminal; and a feedback resonator connected between the signal-in terminal and the signal-out terminal.
