Abstract
The present invention provides a high-frequency circuit capable of acquiring the original transmission characteristics of a filter by preventing capacitive coupling between input and output terminals of the filter externally attached to the integrated circuit and effectively using a mounting space. The high-frequency circuit includes a rectangular integrated circuit 10 having two long sides 10a and 10b and two short sides 10c and 10d and a SAW filter 15, disposed to be adjacent to the short side 10d of the integrated circuit 10, having input terminals 24a and 24b disposed on the long side 10a side and output terminals 28a and 28b disposed on the other long side 10b side. IC output terminals 22a and 22b connected to input terminals 24a and 24b of the SAW filter 15 are disposed on a position of one long side 10a of the integrated circuit 10 on the SAW filter 15 side, and IC input terminals 26a and 26b connected to output terminals 28a and 28b of the SAW filter 15 are disposed on a position of the other long side 10b of the integrated circuit 10 on the SAW filter 15 side.
