Abstract:
A power microwave hybrid integrated circuit, comprising a metal base (1) having recesses (2), naked semicinductor chips (3) disposed in and fixed to the recesses (2) with a binder (4), a dielectric board (5) having a topological metallization pattern (6) on its face side and holes(7) electrically connecting bonding pads (8) of the chips (3) to the topological metallization pattern (6) of the board (5) and filled with an electrically conducting material (9), CHARACTERIZED in that the depth of the recesses (2) in the metal base (1) is selected so that the face surface of the chip (3) and metal base (1) are coplanar, the dielectric board (5) has a shield grounding, metallization (10) on the back side thereof at the places adjoining the metal base (1), the metal base (1) is sealingly joined and electrically connected to the shield grounding metallization (10) of the board (5), and the interconnecting holes (7) are sealingly filled with an electrically conducting material (9), the spacing between the side surface of the chips (3) and the side surfaces of the recesses (2) in the metal base (1) being, of 0.001 to 0.2 mm.
