Abstract

A coaxial juncture assembly 10 has a characteristic impedance Z0′ and comprises an inner conductive formation 32 having opposed first and second ends 34.1, 34.2 which are connectable to an inner conductor of a coaxial cable and an inner conductor 18 of a port respectively. The cable has a characteristic impedance Z0 and the inner conductor has a diameter d1. The formation 32 has an outer diameter d1′, which is larger than d1. A conductive tubular member 36 has an inner diameter D1′, a first end 38.1, a second end 38.2, a slot 40 and an inner surface area A′inner. The member 36 is connectable at end 38.1 thereof to an outer conductor of the cable and at the end 38.2 to an outer conductor of the port. The assembly 10 comprises a dielectric arrangement 42 having a dielectric constant εeff′. At least one of: a) εeff′ and b) A′inner is configured such that a difference between Zo and Zo′ is less than 3% and D1 and D1′ varies by less than 5%.
