More Information
Summary:A micro band-pass filter is disclosed. The micro band-pass filter includes a first resonator having a first inter-digital unit and a second inter-digital unit, which is connected to a first wavelength-impedance converter, on two ends thereof, and a second resonator having a third inter-digital unit and a fourth inter-digital, which is connected to a second wavelength-impedance converter unit on two ends thereof. The second inter-digital unit is adapted to face the third inter-digital unit when forming a first inter-digital coupling structure along with the third inter-digital unit, and the first inter-digital unit is adapted to face the fourth inter-digital unit when forming a second inter-digital coupling structure.
