Abstract

A surface acoustic wave device assembly includes a collective board, first circuit portions provided on the collective board and respectively including first hot terminals and first ground terminals, a second circuit portion provided on the collective board and including second hot terminals and second ground terminals, and a power supply wiring provided on the collective board so as to surround the periphery of the first circuit portions and the second circuit portion. The first circuit portions include surface acoustic wave devices defining band pass filters. The second circuit portion defines a band pass filter. The first ground terminals and first hot terminals, and the second ground terminal are connected to the power supply wiring, the second hot terminals are not connected to the power supply wiring, and pass bands of the surface acoustic wave devices and a pass band of the band pass filter defined by the second circuit portion are the same or substantially the same.
