    摘要: A surface acoustic wave filter having a plurality of the transmission lines, each with one end connected to the surface acoustic wave element and the other end thereof connected to a ground. The transmission lines are divided by an additional transmission line which has multiple connections to a ground electrode at an interval equal to or lower than a wavelength of a using frequency. This structure provides grounds among a plurality of transmission lines and thus isolation among terminals can be increased to improve the filter characteristic.
