DEVICE FOR MOUNTING VERY WIDE BAND MONOLITHIC INTEGRATED MONOLITHIC CIRCUITS.

摘要

The invention relates to a device for mounting very wide band microwave monolithic integrated circuits. …??The integrated circuit chips (5) are mounted on a ferrite support (20). The ferrite support is uniformly metallised (26) on its lower face and carries metallisation pads (21, 24) on its other face. The integrated circuit chips (5) are attached to certain of these pads (24) serving as earth plane. The other pads (21) serve as relays for connecting supply voltages which are applied via a linking wire (7') and via a thin-layered decoupling capacitor (10, 11, 12) carried by the chip. The earth pads (24) are connected to the general earth plane (26) by metallised holes (25). The linking wire (7') is arranged opposite a bare part of the ferrite in order to prevent any parasitic resonance. …??The invention applies in particular to the mounting of very wide band amplifiers made from AsGa integrated circuits. …IMAGE…
