Design and Implementation of 70MHz IF Filter Using Slanted Finger IDT
기울인 전극 구조(Slanted Finger ID)를 이용한 70MHz IF필터의 설계
Abstract
The design and fabrication of the surface acoustic wave(SAW) bandpass filters using slanted finger interdigital electrode transducers(IDTs) is investigated. The slanted finger IDTs are used to design SAW filters with good shape factor, a flat passband, and good out-of-band rejection characteristic. The slanted finger IDTS filter was simulated of three kind of IDTs structure. uniform-uniform IDT, uniform-withdrawal weighting IDTS, withdrawal weighting-withdrawal weighting IDTS. Uniform-withdrawal weighting IDTs structure SAW filters was designed and fabricated on 112
