Abstract
In a connection structure of a radio frequency circuit of the invention, a jumper line of a jumper member is positioned by an insulating base, and the jumper line has a base part that is located inside a cover to be electrically shielded and terminals that are protruded downward from a lower side of the insulating base. In a state that the jumper line of the jumper member intersects a third conductor, the terminals are inserted through a circuit board to be connected to first and second conductors. Therefore, the base part of the jumper line is electrically shielded by the cover, which achieves satisfactory RF characteristics.
