Abstract : The patent describes a monolithic coupled resonator bandpass filter having pairs of input and output electrodes mounted on a crystal resonator such as quartz. A generator is coupled to the high potential side of the input electrodes via an adjustable input impedance. The high potential side of the output electrodes is coupled to a load via an adjustable output impedance. The low potential sides of the input and output electrodes are coupled to ground via adjustable base impedances. The frequency transfer response of the filter may be adjusted by proper adjustment of the various adjustable impedances. Proper adjustment of the base impedances can adjust the symmetry and ripple of the transfer response curve.
