Patent ID: 7176762

Claim:
A radio frequency amplifier comprising: A) a circuit board comprising two dielectric layers, each layer enclosed at least in part by conductive layers, said two dielectric layers defining: 1) a first dielectric layer defining at least a portion of a first elliptical boundary and two foci defining a first focus and a second focus, and 2) a second dielectric layer defining at least a portion of a second elliptical boundary and two foci defining a first focus and a second focus, said second elliptical boundary being geometrically equivalent to said first elliptical boundary; B) a plurality of radio frequency amplifier circuits, each circuit comprising a radio frequency amplifier and having an input at an input location on the first elliptical boundary of said first dielectric layer and an output at an output location on said second elliptical boundary of the second dielectric layer, said output location being at a location on said second elliptical boundary geometrically equivalent to said input location on said first elliptical boundary and each of said amplifier circuits having the same or approximately the same signal transit time; wherein, 1) radio frequency signals broadcasted through the first dielectric layer from its first focus fan out in said first dielectric layer, 2) separate portions of the signals are collected at the boundary of the first dielectric layer into the plurality of amplifier circuits and are amplified separately in the amplifier circuits, 3) the amplified signal from each amplifier circuit is then combined with all other amplified signals in the second dielectric layer by being broadcasted into the second dielectric layer at the boundary of the second dielectric layer, 4) all of the amplified radio frequency signals combine constructively at the second focus of the second dielectric layer and 5) an output of the amplifier is extracted at this second focus.
