ELECTRICAL SURFACE ACOUSTIC WAVE FILTER

摘要

Electrical surface wave filter with a piezoelectric substrate support which carries on its top side an input and output transducer (14, 15), each electrically connected with a printed circuit via external input and output terminals (22, 23), and fastened by its backside on a metal support (11, 12) which comprises grounding terminals (20) integrally formed in one piece. An arrangement of symetrically disposed grounding terminals (20) eliminates the problem of electric cross-talk between the input and output terminals (22, 23).
