Product Profile of Semi-Precision 3Mm High Frequency Sub Miniature Connectors
Oritron Electronics Corporation offers Semi-precision 3mm High Frequency Sub Miniature Connectors. Oritron Electronics Corporation manufactures all types of RF Connectors including BNC, TNC, N, UHF, MINUHF, SMA, SMB, HN, MHV, SHV, VHV, OEC [1.6/5.6] and Inter Series Adapters. Semi-precision 3mm High Frequency Sub Miniature Connectors belong to ORITRON SMA series RF connectors and are characterized by a 1/4"-36 mating thread and a butt mating outer contact. The SMA connector was originally conceived for 0.141" semi-rigid cable, but the concept has broadened to accommodate cables from 0.047" to 0. 250" OD both semi-rigid and flexible. It provides repeatable electrical performance from 0 to 18 GHz and is widely used in microwave systems and subsystems where minimum attenuation and low VSWR are required.
