Abstract:
A microwave hybrid integrated circuit, comprising a dielectric board (1) provided with a topological metallization pattern (2) on the face side thereof and with a shield grounding metallization (3) on its back side, said metallization being electrically connected to a metal base (4), a capacitor (5) electrically connected by its first plate (6) to the base (4), and by its second plate (7) to the topological metallization pattern (2), CHARACTERIZED in that a metallized recess (8) is formed on the face side of the board (1), the metallization of which recess serves as the first plate (6) of the capacitor (5), a remaining portion (9) of the board (1) above or below the recess (8) serves as the dielectric of the capacitor (5), while the second plate (7) thereof is located on the face side of the board (1) and makes a part of the topological metallization pattern (2), the remaining board thickness in the recess (8) being equal to 1-400 .mu.m.
