Patent ID: 7187256

Claim:
A package comprising: a substrate including an upper surface ground plane connected to a lower surface ground plane by vias through the substrate; a die located on the upper ground plane and including a die pad; a transmission path including: on the upper surface of the substrate, a bonding pad connected to a first transmission line itself connected to a transition pad and on the lower surface of the substrate, a second transmission line connected to the transition pad by a via through the substrate; a wire bond extending from the bonding pad to the die pad; a portion of the upper surface ground plane and the lower surface ground plane connected by vias defining opposing walls on either side of the transmission path for signal isolation; and a low pass filter for compensating wire bond inductance, the filter including: a first capacitance formed between the bonding pad and at least the lower surface ground plane, the wire bond inductance, and a second capacitance formed between the die pad and at least the upper surface ground plane.
