SAW FILTER

摘要

Surfaces acoustic wave filter equally transfers surface acoustic wave to output and is used in the television monitor for filtering the middle frequency and delaying the signals. This filter improves the anti-vibration and anti-resonance characteristics of surface wave filter. The overlaid center lines (c,c') are declined with the centered lines (A,A') of the surface acoustic wave filter. One of input electrodes, positive or negative electrode, forms the electrode finger in order to sample the electrode, the selected electrode forms the electrode finger separated 1/8 &lgr;0, from the peak area in the electrode.
