ABSTRACT:
An integrated circuit is mounted on a printed board in a state in which a first edge thereof is located to face to a first side of the printed board and a second edge adjacent to the first edge is located to face to a second side adjacent to the first side of the printed board. A power supply terminal provided on the first edge of the integrated circuit, an AGC terminal and an oscillator terminal respectively provided to a third edge are connected to external terminals via conductive patterns extended to the first side on the printed board. An electrode for measurement is provided in the vicinity of the second side on the printed board and an intermediate frequency output terminal provided on a second edge of the integrated circuit is connected to the electrode via a conductive pattern extended from the second edge to the second side on the printed board.
