Patent ID: 7315455

Claim:
A surface-mounted electronic component module comprising: a wiring substrate having wiring patterns formed on one side and external connection terminals formed on the other side, the wiring patterns and the external connection terminals being connected with each other via holes or through holes; a plurality of electronic component devices mounted on the one side of the wiring substrate, wherein the plurality of electronic component devices include a surface acoustic wave filter that is fastened face up to the one side of the wiring substrate, having a connection terminal, and a semiconductor chip that is fastened face down to the one side of the wiring substrate; a bonding wire connecting the connection terminal of the surface acoustic wave filter with the semiconductor chip or with one of the wiring patterns formed on the one side of the wiring substrate, the bonding wire having an inductance that eliminates ripples in a frequency band characteristic of the surface acoustic wave filter to which one terminal of the bonding wire is connected; and an exterior resin layer formed on the wiring substrate which covers the plurality of electronic component devices, and the bonding wire.
