HIGH FREQUENCY CIRCUIT BOARD, HIGH FREQUENCY SIGNAL MEASURING PROBE AND HIGH FREQUENCY SIGNAL MEASURING METHOD EMPLOYING IT

摘要

PROBLEM TO BE SOLVED: To measure the high frequency signal from a high frequency circuit on a high frequency circuit board accurately while reducing the size thereof. ;SOLUTION: A conduction path 10 from a high frequency circuit to an antenna is formed on one side of a circuit board 1 having the opposite side arranged with a measuring land terminal 22 comprising a main land terminal 23 and an outer land terminal 24 disposed oppositely to the conduction path 10. The main land terminal 23 is connected through a through hole 28 with the conduction path 10. A measuring probe 30 comprises inner and outer conductors 32, 33 formed coaxially through an insulating member 33. The inner conductor 32 projects slidingly from the forward end of the outer conductor 33. The inner and outer conductors 32, 33 are brought into contact with the main land terminal 23 and the outer land terminal 24, respectively, and a high frequency is taken out from the measuring land terminal 22 and measured.;COPYRIGHT: (C)1999,JPO
