ABSTRACT:
A microwave attenuator is constructed on an insulative substrate which supports a resistive region, input/output electrodes and shunt electrodes. The shunt electrodes are preferably constructed using trapezoidally shaped portions on the face of the insulative substrate, on which the resistive region is formed, to increase the width of the electrodes. The shunt electrodes extend down to a ground plane on the face of the insulative substrate opposite the face on which the resistive region is formed. In one embodiment, the shunt electrodes form a wide strip on the outside of a rectangular substrate. In another embodiment, the shunt electrodes extend from the resistive region through holes positioned close to the resistive region. In a third embodiment, the insulative substrate is formed in a block H-shape with the resistive region formed on the cross portion on one of the "H" faces and the shunt electrodes connects the resistive region to the ground plane which is formed on the opposing "H" face, by passing between the long parallel portions of the block H-shape.
