Abstract
A transmitter includes an RF board having a circuit for processing high frequency signals, an IF board having a circuit for processing intermediate frequency signals, a shield plate formed of a conductive material arranged between the boards for shielding electromagnetic waves generated from the circuits, a board-to-board connecting wire inserted to a through hole based by a gap sufficient to avoid electric influence from an inner wall surface of the through hole provided in the shield plate, to be connected to through hole lands provided on the RF board and a IF board, respectively, and connectors formed of an insulating material and attached near opposite ends of the board-to-board connecting wire and sandwiching the shield plate, for fixing the board-to-board connecting wire to the shield plate. This provides a wiring connection structure that facilitates connection between circuit boards with each other and stably realizes normal signal transmission.
