Abstract:
1. A coaxial electrical connector for mating a coaxial transmission line of first impedance having a center conductor and an outer conductor with an electrical device of second impedance, said connector comprising: a substantially cylindrical outer conductor having spaced first and second end portions, and an elongate center portion intermediate said end portions, said cylindrical outer conductor having an axial bore therethrough; a dielectric insulator fixed within said bore at said center portion; a coupling mechanism mating said first coaxial transmission line to said substantially cylindrical outer conductor; and an inner conductor within said insulator and extending coaxially within said bore, said inner conductor having first and second end portions corresponding to said first and second end portions of said cylindrical outer conductor and a center portion corresponding to said center portion of said cylindrical outer conductor, said first end portions interfitting with the coaxial transmission line such that said first end portion of said inner conductor mates with the center conductor, and said first end portion of said cylindrical outer conductor mates with the outer conductor, and said second end portions being mateable with the electrical device, wherein the substantially cylindrical outer conductor, inner conductor, and the dielectric insulator cooperatively provide for a transformer impedance for matching the first and second impedance, and wherein a transforming length of said center portions comprising a distance from a first impedance transition between the first impedance and the transformer impedance to a second impedance transition between the transformer impedance and the second impedance.
