Abstract
Abstract A subcombination of a coaxial broadband frequency multiplier, the subcombination consisting of coaxial connector jack and plug bodies connected together in electrical engagement with each other and having an axially aligned opening through the entire jack and plug bodies, the opening carrying along the axis thereof a varactor having oppositely disposed terminals with a first center conductor in electrical engagement with one of the terminals and extending axially in one direction in the opening and a second center conductor in electrical engagement with the other terminal and extending axially in the opposite direction in the opening, and an insulator in the jack and plug bodies fixing the respective center conductors in place in the opening and separated from the jack and plug bodies.

Claim 1
Independent Claim
264 words
For a coaxial frequency multiplier with input frequency under 1,000 megacycles, the combination of a coaxial connector plug body and a coaxial connector jack body coupled together and having an axially aligned opening therethrough, a varactor in said opening and having a pair of terminals, a first center conductor in electrical engagement with one of said terminals and in the form of a female center conductor extending from said terminal in axial alignment with said opening in the direction of said jack body, a second center conductor in electrical engagement with the other of said terminals and in the form of a male center conductor extending from said other terminal in axial alignment with said opening in the direction of said plug body, a dielectric member coupled to the inside of said jack body and to said female center conductor rigidly fixing said female center conductor in place as a reference for said varactor, a second dielectric member in said plug body mounting said male center conductor to slide in said axial alignment with said opening, a sleeve of electrically conductive material in said plug body forming the part of said axially aligned opening circumscribing said varactor and having a cross-sectional relation to the cross section of said varactor substantially the same as the crosssectional relation of the remainder of said axially aligned opening to the cross section of said center conductors, and a bushing of resilient material about said sleeve in said plug body for holding said sleeve in said axial alignment in said plug body in the absence of said jack body.
