8、cience and Technology Agency Glasnevin Report on the Voting; CECC(Secretariat) 1320 July 1983 CECC(Secretariat)1436 Series MCX connectors use the same inner contact and dielectric diameters as series SMB connectors (EN 122 130) but have smaller outside dimensions requiring considerably less space th
9、an series SMB connectors. Series MCX connectors have a characteristic impedance of 50 Q and are normally used for low power applications, in conjunction with flexible coaxial cables having a dielec- tric diameter of 0,86 mm to 1,6 rnm. The connectors are usable up to a frequency of at least 3 GHz, a
10、nd may be used at higher frequencies if a reflection factor greater than 0,15 can be tolerated for straight connectors and 0,24 for right-angle styles.
