PROBLEM TO BE SOLVED: To provide a surface acoustic wave device by which a convolution output signal is easily detected. SOLUTION: At least part of input side external circuits 10a, 12a or an output side external circuit 11 is arranged in a package containing a surface acoustic wave convolver element in input side external circuits 10a, 10b consisting of at least part or all of an impedance matching circuit, a filter and an amplifier and an output side external circuit 11 consisting part or all of an impedance matching circuit, a filter and an amplifier. |
