Abstract:
A high-frequency module comprising:a dielectric board; first and second cavities closed by closures joined to an upper surface of said dielectric board, the cavities being independent from each other; first and second high-frequency devices mounted on the upper surface of said dielectric board at positions in said first and second cavities, respectively; first and second high-frequency signal transmission lines arranged on the upper surface of said dielectric board at positions in said first and second cavities, respectively, and having first ends electrically connected to respective high-frequency devices; a third high-frequency signal transmission line disposed on a lower surface of said dielectric board; and an electrically conductive member mounted on the lower surface of said dielectric board and electromagnetically shielding said third high-frequency signal transmission line; wherein a second end of said first high-frequency signal transmission line and a second end of said second high-frequency signal transmission line are electromagnetically coupled to said third high-frequency signal transmission line, whereby said first and second high-frequency devices are coupled to transmit high-frequency signals therebetween.
