Radio-frequency connectors. Part 10: R.F. coaxial connectors with inner diameter of outer conductor 3 mm (0.12 in) with snap-on coupling - Characteristic impedance 50 ohms (Type SMB)

Concerns patterns for r.f. coaxial connectors which may preferably be used with r.f. cables 96 IEC 60050-1 or 96 IEC 60050-2 of IEC 60096-2: Radio-frequency cables, Part 2: Relevant cable specifications. These connectors are for low power. They have a snap-on coupling mechanism and are commonly known as Type SMB.

Radio-frequency connectors - Part 11: R.F. coaxial connectors with inner diameter of outer conductor 9.5 mm (0.374 in) with screw coupling - Characteristic impedance 50 ohms (Type 4.1/9.5)

This standard concerns r.f. coaxial connectors for use with r.f. cables, both flexible and semi-rigid, with air dielectric interface and high mechanical stability to withstand severe environmental exposure. The connectors provide low reflection in the microwave region up to 14 GHz and they are watertight and air-tight against a pressure difference of 3 bar.

Radio-frequency connectors - Part 13: R.F. coaxial connectors with inner diameter of outer conductor 5.6 mm (0.22 in) - Characteristic impedance 75 ohms (Type 1.6/5.6) - Characteristic impedance 50 ohms (Type 1.8/5.6) with similar mating dimensions.

Radio-frequency connectors. Part 15: R.F. coaxial connectors with inner diameter of outer conductor 4.13 mm (0.163 in) with screw coupling - Characteristic impedance 50 ohms (Type SMA)

Concerns r.f. coaxial connectors for use with semi-rigid and flexible r.f. cables and specially intended to be used for microwave application requiring high performance. This type of connector is known commercially as the SMA connector.

Radio-frequency connectors - Part 23: Pin and socket connector for use with 3.5 mm rigid precision coaxial lines with inner diameter of outer conductor of 3.5 mm (0.1378 in)

Covers a precision pin and socket connector for use with 3.5 mm rigid precision coaxial lines so as to minimise test apparatus errors attributable to coaxial connectors. These connectors are constructed so as to affix on the 50 ohm, 3.5 mm rigid precision coaxial line described in IEC 60457-5, and to provide low reflection to 34 GHz.

Radio-frequency connectors - Part 7: R.F. coaxial connectors with inner diameter of outer conductor 9.5 mm (0.374 in) with bayonet lock - Characteristic impedance 50 ohms (Type C)

Gives the dimensions for r.f. coaxial connectors which may preferably be used with r.f. cables 96 IEC 60050-7. These connector patterns are for medium power, quick disconnect applications using a bayonet type coupling mechanism.

Rigid precision coaxial and their associated precision connectors. Part 2: 50 ohms 7 mm rigid precision coaxial line and associated hermaphroditic precision coaxial connector.

Describes the mechanical, electrical and environmental specifications of the 7 mm precision connector, the reflection coefficient and attenuation of which has to be measured up to 18 GHz.

Rigid precision coaxial and their associated precision connectors. Part 5: 50 ohms 3.5 mm rigid precision coaxial line with provision for mounting connectors.

Gives geometrical configuration of the rigid precision coaxial line and the provision mounting connectors.

High-voltage coaxial connectors used in nuclear instrumentation

Applies to coaxial connectors associated with electrical measuring instruments used in nuclear instrumentation. Establishes standard dimensions of the mating parts, construction and mounting rules, voltage rating and test voltages, mininium insulation requirements, maximum contact resistances and operating conditions for two types of high-voltage connectors.

Radio-frequency connectors - Part 16: Sectional specification - RF coaxial connectors with inner diameter of outer conductor 7 mm (0,276 in) with screw coupling - Characteristics impedance 50 ohms (75 ohms) (type N)
