Title: Surface acoustic wave filter
Inventor: ATOMIYA TADAMASA
IPC: H03H9/64
Filed: 1995-08-14
Abstract: PROBLEM TO BE SOLVED: To improve a steep attenuation characteristic by setting a distance between a reflector and an IDT(interdigital transducer) of a 2nd 1-port SAW (surface acoustic wave) resonator to allow the 2nd 1-port SAW(surface acoustic wave) resonator to generate a spurious component. SOLUTION: A distance between the IDT and the reflector in each of SAW resonators 23-27 is set as indicated in a specific table. That is, while a distance between an IDT 24a (26a) and a reflector 24b (24c) in a resonator 24 (26) being a series resonator is set to be 0.5λ, the distance of a parallel resonator 23 (25, 27) is set smaller than 0.5λ. Then a frequency of spurious radiation produced between a resonance frequency and an anti-resonance frequency in the resonators 23, 25, 27 is set between the resonance frequency of the resonators 23, 25, 27 and the pass band of the SAW filter 21. Thus, the attenuation in the vicinity of the pass band at a block frequency lower than the frequency of the pass band is considerably improved.
