<p>Interdigital transducers (IDT electrodes), reflectors, etc., are formed on a piezoelectric substrate. An unbalanced terminal (109) is connected to an input/output terminal (113). A first inductor (112) is connected between a first terminal (110), which is one of the balanced input/output terminals, and a second terminal (111), which is the other of the balanced input/output terminals. Further, a second inductor (116) is connected between the first terminal (110) in the balanced input/output terminals and a further input/output terminal (114), and the second terminal (111) in the balanced input/output terminals is connected to a third input/output terminal (115).</p> |
