ABSTRACT:
A surface acoustic wave apparatus includes a first filter and a second filter, which are integrated into one package, and, filter signal terminals of the first and second filters are connected to package signal terminals of the package through different paths which are insulated from each other. A signal line extended from filter signal terminals is connected to one common terminal outside the package. The signal line and the common terminal define a coupling section. An inductance device is connected in parallel to the coupling section as a matching circuit.
