WIRELESS MODULE
A wireless module includes a first board ( 11 ) on which a mounting component of a wireless circuit is mounted, and a second board ( 12 ) which is laminated on the first board ( 11 ). The first board ( 11 ) and the second board ( 12 ) are electrically connected together by a connecting member ( 18 ) such as a Cu core ball. Laterally to the connecting member ( 18 ), a conductive member ( 23 ) for impedance adjustment is provided at a position at a predetermined distance from the connecting member ( 18 ), such that the signal path of the connecting member ( 18 ) has predetermined impedance.
1 . A wireless module, comprising:
a first board on which a mounting component of a wireless circuit is mounted;
a second board which is laminated and disposed on the first board;
a connecting member which forms a gap allowing mounting of the mounting component between the first board and the second board, the connecting member electrically connecting the first board and the second board, wherein the connecting member includes a conductor forming a signal path; and
a conductive member which is arranged at a position separate by a predetermined distance from the conductor of the connecting member, the conductive member being connected to a ground of the first board or the second board wherein
the connecting member is connected to the mounting component via a signal line having a predetermined width,
a diameter of the connecting member is greater than e predetermined width of the signal line, and
the predetermined distance between the conductive member and the conductor of the connecting member is substantially the same as the diameter of the connecting member.
2 . (canceled)
3 . The wireless module according to claim 1 , wherein
the connecting member is a member of a conductor, and
the conductive member is a separate member different from the connecting member.
4 . The wireless module according to claim 1 , wherein
the connecting member includes a signal line conductor and a ground conductor which is arranged at a position at a predetermined distance from the signal line conductor, and the ground conductor functions as the conductive member.
5 . The wireless module according to claim 4 , comprising:
a wiring pad which is connected to the connecting member of the ground conductor and formed on the first board or the second board; and
a via which connects the wiring pad and the ground of the first board or the second board.
6 . The wireless module according to claim 1 , wherein
the conductive member is arranged so that the signal path of the connecting member has predetermined impedance.
