In an acoustic wave filter device, first and second longitudinally coupled resonator SAW filters are provided on a piezoelectric substrate. The first and second longitudinally coupled resonator SAW filters are connected in parallel to each other. The first and second longitudinally coupled resonator SAW filters are withdrawal-weighted. The withdrawal weighting in at least the longitudinally coupled resonator SAW filter is different from the withdrawal weighting in the other longitudinally coupled resonator SAW filter.       Recently Added Patents High strength lightweight vehicle and an improved method for producing same Dynamic selection of random access channel configurations Configuration of a basic input/output system (BIOS) based on a series of follow up questions tailored to user type Central control braking system Dual bar adjustable bow sight Display substrate, method of manufacturing the same and display device having the same Infrastructure for mediation device to mediation device communication   Randomly Featured Patents Oil-soluble zinc cyclic hydrocarbyl dithiophosphate-succinimide complex and lubricating oil compositions containing same Negative electrode material for nonaqueous secondary cells, negative electrode for nonaqueous secondary cells, and nonaqueous secondary cell Cooling system with a variable maximum operation level Wheel alignment rim clamp claw Apparatus for making plates for printing Recording apparatus for informing an operator of an inconsistency between the kind of sheet designated by the operator on which recording is desired to occur and the kind of sheet actually set Artificial erection device Temperature moderation system and method with temperature difference considerations between indoors and outdoors Membrane filter system Method and apparatus for application-driven storage provisioning on a unified network storage system © 2006-2008 PatentGenius.
