Abstract:
An asymmetrical response bandpass filter, comprising:a first row of four series coupled resonator cavities, wherein a first resonator cavity is coupled to a second resonator cavity, said second resonator cavity is coupled to a third resonator cavity, and said third resonator cavity is coupled to a fourth resonator cavity; a second row of four series coupled resonator cavities, wherein a fifth resonator cavity is coupled to a sixth resonator cavity, said sixth resonator cavity is coupled to a seventh resonator cavity, and said seventh resonator cavity is coupled to an eighth resonator cavity; an input terminal in communication with said first resonator cavity of the first row; an output terminal in communication with said eighth resonator cavity of the second row; and parallel couplings which connect said first and seventh resonator cavities and said eighth and second resonator cavities, respectively.
