Mini-UHF Series

Mini-UHF coaxial connectors are designed for use in applications from DC to 2.5GHz where size, weight and cost elements are critical.
These miniature 3/8-24 thread size connectors provide excellent RF performance and are impedance matched to 50 Ohm cable.
Mini-UHF connectors combine electrical characteristics, small size and light weight at a relatively inexpensive cost for many coaxial connector applications.
