<P>PROBLEM TO BE SOLVED: To facilitate the inspection of a local oscillation frequency of a local oscillation circuit at the stage of product inspection. <P>SOLUTION: A lead-out pattern 13 is formed on a printed circuit board 11 provided with a circuit for wireless communication including the local oscillation circuit 10. One end of the lead-out pattern 13 is connected to the output (A) of the local oscillation circuit 10 via a coupling capacitor 15. The other end of the lead-out pattern is connected to a terminal 12a for inspection of a connector 12. The local oscillation signal of the local oscillation circuit 10 is outputted from the terminal 12a for inspection. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
