Title: Acoustic surface wave device
Inventor: MORIMOTO MIKIO
IPC: H03H3/08
Filed: 1983-02-08
Abstract: PURPOSE:To prevent an acoustic surface wave device from deteriorating in characteristics by varying the width of a shield electrode and thus correcting the phase shift of an acoustic surface wave due to the difference in electrode density of an acoustic surface wave transducer. CONSTITUTION:The shield electrode 11 is formed crossing an acoustic surface wave propagation path between an acoustic surface wave transducer and a normal acoustic surface wave transducer 2 on a transmission side. The width of this shield electrode 11 is narrow (l2) at the center part of the acoustic surface wave transmission line and wide (l1) on both side parts. When the l1 and l2 are so determined that the phase shift between the center part and both side parts of the transmission line when the wave passes through the shield electrode 11 is equal to the phase shift before the wave passes through the shield electrode 11, an acoustic surface wave which has a phase distribution as shown by a curve 12 is corrected so that the wave is in phase at both side parts of the transmission line after passing through the shield electrode 11, obtaining a phase distribution as shown by a curve 13. Thus, the phase shift of the acoustic surface wave due to the difference in electrode density of the transmission-side transducer 1 is corrected by the shield electrode 11 to prevent deterioration in characteristics.
