Hybrid integrated circuit device

Abstract

Abstract PURPOSE:To improve the deterioration in isolation between terminals of a transmitter and a receiver and to reduce insertion loss by cutting off a part of a main line of a strip line, arranging an electrode equipotential to a sub line between the cut and opposed main lines on the main line axis, connecting a semiconductor active element placed on the electrode to both ends of the main line with a metallic fine wire. CONSTITUTION:A part of the main line 9 of the strip line is cut off, and the electrode equipotential to the sub line 14 is arranged between the cut and opposed main lines 9, 9 on the same plane as the main lines 9, 9 so as not to be in contact with the main lines 9, 9. Since an active element 13 is arranged in the main lines 9, 9, bonding lines 11, 12 connecting the main lines 9, 9 and a diode are made very short, the inductance is decreased and the cut main lines 9, 9 are isolated, then the impedance of the active element 13 is effected directly on the main lines. As a result, the degree of short-circuit is improved, the isolation between the transmitter terminal 6 and the receiver terminal 8 and the insertion loss between the transmitter terminal 6 and an antenna terminal 7 are improved and the insertion loss between the antenna terminal 7 and the receiver terminal 8 is improved.
