Latest Patents

One of his latest patents is titled "Frequency Selective Limiter with Flat Limiting Response." This invention is directed to a frequency selective limiter (FSL) that utilizes a pair of planar ferrite members with planar surfaces in confronting relationship. At least one signal-carrying conductor is supported between the ferrites and closely coupled to them. A magnetic biasing field is established, with field lines disposed at an angle relative to the conductor, resulting in increased attenuation at low frequencies and a relatively flat limiting characteristic across the bandwidth. The conductor may lie in a plane parallel to or transverse to the field lines, with one embodiment featuring a zigzag configuration in the plane of the field.

Another significant patent is "Frequency Selective Limiter with Welded Conductors." In this invention, first and second ferrite members have confronting planar surfaces, with at least one conductor located on the surface of each ferrite in intimate contact. Each conductor on the first ferrite is a mirror image paired with a corresponding conductor on the second ferrite. The paired conductors have confronting end surface portions that are intimately bonded or welded in electrical contact, making each of the paired conductors electrically equivalent to a single conductor closely coupled to the ferrites. This design eliminates the need for additional bonding to secure the ferrite members together, and an external conformal ground plane is more securely deposited in the regions where the ferrites abut.
