Abstract
Abstract A low impedance transmission line consisting of substantially coextensive, thin conductive straps which overlap one another, and are connected to respective opposite terminals of a high voltage rectifier stack, bypasses RF energy from a radio frequency transmitter connected to the high voltage rectifier stack around the stack to prevent damage to the stack diodes.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
153 words
In combination, a low impedance transmission line and a high voltage rectifier stack; said high voltage rectifier stack comprising a plurality of series-connected diodes extending between first and second spaced terminals, and a mounting support for mounting said plurality of diodes and said first and second terminals; said first and second terminals being positioned at opposite ends of said mounting support; said low impedance transmission line comprising first and second thin, elongated, closely spaced conductors each having a terminal end and a free end; said terminal ends of said first and second conductors being electrically connected to and mechanically supported by said first and second terminals respectively; said free ends of each of said first and second conductors terminating just short of the terminal end of the other, whereby said first and second conductors are substantially coextensive with one another and define a low impedance transmission line in parallel with said rectifier stack.
Claim 2
Dependent Claim
153 words
In combination, a low impedance transmission line and a high voltage rectifier stack; said high voltage rectifier stack comprising a plurality of series-connected diodes extending between first and second spaced terminals, and a mounting support for mounting said plurality of diodes and said first and second terminals; said first and second terminals being positioned at opposite ends of said mounting support; said low impedance transmission line comprising first and second thin, elongated, closely spaced conductors each having a terminal end and a free end; said terminal ends of said first and second conductors being electrically connected to and mechanically supported by said first and second terminals respectively; said free ends of each of said first and second conductors terminating just short of the terminal end of the other, whereby said first and second conductors are substantially coextensive with one another and define a low impedance transmission line in parallel with said rectifier stack.
Claim 3
Dependent Claim
