Title: Surface acoustic wave filter
Inventor: HIKINO OSAMU
IPC: H03H9/64
Filed: 1990-02-16
Abstract: PURPOSE:To suppress the effect of the diffraction effect of simple electrode structure by expanding a cross width of an electrode finger opposite to each other so as to suppress the effect of a diffraction wave without changing a surface acoustic wave exciting strength between the electrode finger pairs opposite to each other. CONSTITUTION:Electrode fingers 1, 3 prolonged from upper and lower buses 4, 5 and a stray electrode 2 have cross parts whose cross width is W1 and W2 independently electrically of an adjacent opposite electrode. Since a level of a floating electrode 2 has an intermediate level between a level of the electrode finger 1 and a level of the electrode finger 3, the phase of a surface acoustic wave element is an exciting phase obtained at the two cross parts whose cross width is W1 and W2 to give excitation of the strength proportional to the cross width W1 and W2. Thus, the excitation of the surface acoustic wave of the desired strength is obtained by selecting properly the cross width W1 and W2 because the surface acoustic wave excited by the floating electrode 2 and the electrode fingers 1, 3 is propagated while being cancelled together. Thus, the diffraction effect is suppressed.
