Coaxial impendance transformer

I1 impedance transformer is designed to match coaxial microwave paths with 50 Ohm and 75 Ohm impedances. Impedance transformer provides measurement of device parameters in 50 Ohm coaxial path, using vector and scalar network analyzers with 75 Ohm measuring ports and vice versa. Impedance transformers operate at frequencies between 0 and 3 GHz and temperatures between -60 °C and +85 °C. Their bodies and nuts are made of stainless steel. Their central conductors are made of tempered beryllium bronze plated with wear-proof gold, which provides at least 5000 connect/disconnect cycles.
