High frequency hybrid integrated circuit

Abstract

Abstract PURPOSE:To reduce the size of a circuit and increase the density of the circuit by a method wherein a part of a circuit composed of asymmetrical strip lines provided on one of the surfaces of a dielectric substrate is formed on a facing part in a box type dielectric cap to form approximately symmetrical strip lines. CONSTITUTION:Line conductor patterns 3a and 3b are formed on one of the surfaces of a dielectric substrate 1. A protruding part 5 is formed in a box type dielectric cap 4 which has a lower opening at a position facing the line conductor pattern 3b and a grounding conductor 6 is formed on the surface of the protruding part 5. One end of the conductor 6 is connected to the conductor 2 of the substrate 1 with solder 7. The electric field of the strip line 3b in the part where the conductor 6 is provided is formed between the conductors 2, 3b and 6 and the impedance of the strip lines can be reduced compared to the impedance when the conductor 6 does not exist without increasing the occupying area of the circuit.
