Abstract
A multi-pole monolithic crystal filter with at least three acoustically coupled resonators (50,52,54) on a piezoelectric blank (56). Each resonator (50,52,54) has associated top and bottom electrodes (70,72,74,76,78,80). An input connection (62) is coupled to the top electrode (70) of a first resonator (50) and a ground connection (64) is coupled to the bottom electrode (72) of the first resonator (50). An output connection (68) is coupled to the bottom electrode (80) of a last resonator (54) and a ground connection (66) is coupled to the top electrode (78) of the last resonator (54). The top and bottom electrodes (74,76) of each of the remaining resonators (52) are coupled to each other.
