Abstract:
1. A semiconductor package comprising: a base substrate on which semiconductor elements are disposed; a covering member which is provided to the base substrate, which covers the semiconductor elements, and which includes an opening at an end thereof at the side of the base substrate; and a connector substrate having a first surface and a second surface opposite to the first surface, the connector substrate provided on the base substrate in a manner that the connector substrate closes the opening, which includes a first high-frequency signal line in an area located inside the covering member on the first surface, and which includes a second high-frequency signal line on the second surface, the second high-frequency signal line being electrically connected to the first high-frequency signal line; wherein the first high-frequency signal lire and the base substrate provide a first micro-strip line part, the second high-frequency signal line and the base substrate provide a second micro-strip line part, and impedance of the first micro-strip line part is the same as impedance of the second micro-strip line part.
