112620

Overview

The Amphenol RF 112620 is a BNC coaxial attenuator housing designed for radio frequency applications. It operates within a frequency range of 0 GHz to 6 GHz and supports both 50 Ohm and 75 Ohm impedance configurations. The component utilizes a bayonet coupling mechanism, enabling quick connect and disconnect functionality with a positive locking system that requires only a quarter-turn for mating. This design ensures reliable signal integrity in high-performance environments.

Feature Summary

• Bayonet style connector allowing for quick connect and disconnect
• Positive locking mechanism requiring only a quarter turn for mating
• Supports 50 Ohm and 75 Ohm impedance configurations
• Operates within a 0 GHz to 6 GHz frequency range

Applications

• Military equipment interconnects
• Aerospace system connections
• Industrial device RF links

Procurement Notes

Verify the specific impedance requirement (50 or 75 Ohm) and attenuation value against the project specifications before ordering. Confirm that the bayonet coupling interface matches existing panel or cable assemblies. Ensure the operating frequency does not exceed the 6 GHz maximum rating. Check for any environmental sealing requirements if used in harsh conditions. Cross-reference the manufacturer part number with official distributor catalogs to ensure authenticity and current availability status.

Selection Notes

Select this component when a robust, quick-mating RF connection is required within the 6 GHz bandwidth. The bayonet design offers superior mechanical stability compared to screw-type connectors in vibration-prone environments. Consider the impedance match between the source, load, and transmission line to prevent signal reflection. Evaluate the physical space constraints as the bulkhead or inline form factor must fit the assembly layout. Ensure compatibility with standard BNC mated pairs for seamless integration.

Part Context

This component belongs to the Amphenol RF BNC series, which provides miniature coaxial connectors for various industries. The BNC interface is widely recognized for its reliability and ease of use in test and measurement, as well as communication systems. Amphenol RF manufactures these components to meet stringent performance standards for signal integrity and mechanical durability in demanding applications.

Replacement Considerations

Generic BNC attenuators may serve as substitutes if exact part numbers are unavailable, provided they match the impedance, frequency range, and attenuation value. Verify that the replacement maintains the same bayonet coupling dimensions and locking torque characteristics. Ensure the material composition and plating are compatible with the existing environment to prevent corrosion or contact resistance issues.
