Abstract:
1. A high frequency module comprising: a first dielectric substrate provided with a first and a second waveguide; a second dielectric substrate laminated on said first dielectric substrate and provided with a first cavity and a second cavity, disposed so as to be separate from each other, and said first and second waveguides; a third dielectric substrate laminated on said second dielectric substrate and having a third cavity, inside of which is positioned said first cavity, and a fourth cavity, inside of which is positioned said second cavity, disposed apart from said third cavity and having a slot for communicating to said third cavity, with said first and second waveguides respectively provided outside said third and fourth cavities; a metal conductor provided so as to seal said third and fourth cavities; a plurality of first high frequency circuits installed within said first cavity; a plurality of second high frequency circuits installed within said second cavity; a first connection line provided within said communicating slot and connecting between said first and second high frequency circuits; and a second and third connection line respectively connecting said first and second high frequency circuits with said first and second waveguides.
