ABSTRACT:
A surface acoustic wave filter includes a surface acoustic device on a reception side which has signal terminals for inputting and outputting located in a corner along a diagonal and a surface acoustic wave device on the transmission side which has signal terminals for inputting and outputting at ends on one side. The surface acoustic wave devices are provided on a circuit board such that the signal terminals are located close to each other and connected to a wiring pattern on the antenna side.
