Abstract

Однонаправленный преобразователь для устройства на поверхностных акустических волнах (ПАВ). В одном варианте осуществления устройство включает в себя (1) определенный участок на пьезоэлектрической подложке, в пределах которого находится разомкнутый отражатель, перпендикулярный направлению распространения ПАВ; и пару электродов преобразователя с низкой отражательной способностью, расположенных в пределах этого определенного участка и подключенных к противоположным шинам, причем электроды перпендикулярны направлению распространения ПАВ и размещены так, что центр возбуждения пары электродов находится от отражателя на расстоянии, приблизительно равном семи восьмым длины релеевской волны на центральной частоте ПАВ.
