A converter for SAW filters on a piezoelectric substrate. The converter consists of several groups (Ga, Gb, ...), which are linked in a half-group manner (Ga1, Ga2, ...) with bus-bars (Ph1, Ph2) for two phases (1, 2). These half-groups are alternately distributed to two or more channels (K1, K2, ...) that the finger-electrodes of each phase (1, 2) - seen over all channels - form a more or less gap-free series. Belonging to each channel is a common meandering bus-bar M for both phases 1 and 2. |
