A coaxial cable-connector assembly includes a coaxial cable and a coaxial cable connector. The coaxial cable includes: a central conductor having a connector end; a dielectric layer that overlies the central conductor; and an outer conductor that overlies the dielectric layer having a connector end. The coaxial connector includes: a central conductor extension configured to mate with a mating connector at one end; a first insulative layer interposed between an opposed second end of the central conductor extension and the connector end of the central conductor; an outer conductor extension configured to mate with a mating connector at one end; and a second insulative layer interposed between an opposed second end of the outer conductor extension and the connector end of the outer conductor. This configuration can reduce and/or avoid PIM within the connection of two coaxial connectors.
