Patent ID: 7692515

Claim:
A component comprising: a first filter comprising a first structure, the first structure comprising one of a transducer and a reflector, the first filter further comprising a second structure, the second structure comprising one of a transducer and a reflector; a substrate on which the first and second structures are arranged; wherein: the first structure has an approximately uniform layer thickness and an approximately uniform composition, the second structure has an approximately uniform layer thickness and an approximately uniform composition, and at least one of the layer thickness and composition of the first structure differs from the layer thickness or composition of the second structure, and the component is configured to operate with acoustic waves; wherein the first structure is in a first acoustic track comprising a series resonator and has a uniform metallization ratio, the second structure is in a second acoustic track comprising a parallel resonator and has a uniform metallization ratio, the metallization ratio of the first structure being different than the metallization ratio of the second structure; and wherein the metallization ratio in the parallel resonator is less than the metallization ratio in the series resonator.
