Abstract
An amplifier GaAs MMIC for microwave band applications includes a ground electrodehaving a via hole groupcomposed of three via holesfilled with plated metalsthat are formed adjacently. The interaction thereby generates high frequency electromagnetic bonding, which reduces the ground inductance. According to the MMIC, the ground inductance of the via hole may be reduced while decrease of a strength and increase of a size being restrained.
