Patent ID: 8422980

Claim:
A high-frequency circuit comprising: a rectangular integrated circuit having first and second sides which face with each other and third and fourth sides which face with each other; and a high-frequency filter disposed adjacent to the third side of the integrated circuit, the high-frequency filter having: an input terminal disposed on a side located on a same side as the first side; and an output terminal disposed on another side located on a same side as the second side, wherein the rectangular integrated circuit comprises: a first terminal configured to output a high-frequency signal, the first terminal being provided on the first side and connected to the input terminal of the high-frequency filter; and a second terminal configured to receive a filtered high-frequency signal, the second terminal being provided on the second side and connected to the output terminal of the high-frequency filter, and wherein the high-frequency circuit further comprises: a ground pattern provided between the first side and the second side along a center line of the integrated circuit, the ground pattern extending to the high-frequency filter between the input terminal and the output terminal along a center line of the high-frequency filter.
