Abstract: An over-voltage surge protection device includes a circuit board having a signal carrying conductive member with a plurality of nodes positioned therealong, and a conductive member running to ground positioned therealong. The nodes on the signal carrying member and the ground conductive member each extend along a common path with corresponding ones of the signal carrying nodes positioned in adjacent, but spaced relation to the ground member, wherein the conductive member running to ground is formed along the interior of the main body enclosing the circuit board and the signal carrying conductive member. The peripheral edges of the nodes accumulate and discharge transient high voltage surges. The nodes can be shaped in the form of triangles due to this particular geometry's favorable ability to accumulate and discharge voltage, but may also be formed in a variety of other geometries.

Abstract: A cable system, and a method for configuring a path of a cable system, wherein the group delay caused by one or more amplifiers having diplex filter networks is substantially equalized over all frequencies within a predetermined band by the use of one or more all-pass delay equalizers. A method of configuring a path includes steps of determining a delay versus frequency characteristic of the path within the predetermined frequency band, and providing from one to a plurality of all-pass delay equalizers in the path, wherein a collective delay versus frequency characteristic of the all-pass delay equalizer(s) within a predetermined frequency band is a mirror image of that caused by the amplifier(s), such that all frequencies within the predetermined frequency band are delayed by substantially the same amount and hence all frequency components of a signal arrive at a receiver at substantially the same time.

Abstract: The present invention provides an over-voltage surge protection device comprising a printed circuit board having a signal carrying conductive member having a plurality of nodes positioned therealong, and a conductive member running to ground also having a plurality of odes positioned therealong. The nodes on the signal carrying member and ground member extend along a common path with corresponding ones of the signal carrying nodes positioned in adjacent, but spaced relation to the ground nodes. The peripheral edges of the nodes accumulate and discharge transient high voltage surges. Preferably the nodes are shaped in the form of triangles due to this particular geometry's favorable ability to accumulate and discharge voltage, but may be formed in a variety of geometries.
