HYBRID INTEGRATED CIRCUIT FOR HIGH FREQUENCY MICROWAVE AND ITS MANUFACTURE

摘要

PURPOSE:To realize a high frequency microwave use hybrid integrated circuit miniaturized entirely by arranging a semiconductor chip and an integrated circuit chip to a recessed part in which a ground conductor is exposed. CONSTITUTION:A ground conductor 2 is inserted between a base 9 and a thin base 8 in a transmission line section 3 such as a microstrip line, a recessed part 10 on which the ground conductor 2 is exposed to the thin base 8 and a circuit chip 6 is arranged to the recessed part 10. Thus, while the characteristic impedance is kept to a prescribed value, the conductor 4 is decreased and the projection of a semiconductor and integrated circuit chip 6 and a lead wire 7 from the transmission line 3 such as the microstrip line is reduced, then the entirely small sized high frequency microwave use hybrid integrated circuit is realized.
