Coaxial adapter SMA female to SMA female — OEM CA-SF-SF

Coaxial adapter SMA female to SMA female — OEM CA-SF-SF provides a compact mechanical interface to join two coaxial cables or modules terminated with SMA male connectors. Designed for RF and microwave signal linking, this SMA female-to-female adapter enables extension of cable runs, connection of antennas or test fixtures, and temporary coupling of equipment in lab, field and installation environments. The adapter is compact and passive, offering a direct mechanical and electrical path between SMA male terminations.

Advantages

The adapter delivers a simple and reliable mechanical connection with minimal handling complexity. Its SMA female-to-female configuration eliminates the need to re-terminate or replace cables when joining two male-terminated lines. The compact form factor reduces space requirements in dense setups and allows easy placement in racks, test benches, or tight enclosures. Being a passive component, it requires no power and introduces only the inherent insertion loss and VSWR characteristics typical for SMA interfaces.

Suitable for

• Extending coaxial cable runs by joining two SMA male-terminated cables
• Connecting antennas, RF modules, or transceivers with SMA male connectors
• Temporary coupling during testing, measurement, and troubleshooting in laboratories
• Field installations where quick joins are required without re-terminating cables

Key specifications

• Connector type: SMA female to SMA female
• Application: RF and microwave signal linking
• Mechanical: Compact, inline coupler design suitable for tight spaces
• Electrical characteristics: Passive device with typical SMA insertion loss and VSWR behavior (dependent on frequency and quality of mating connectors)
• Use environment: Laboratory, field, and installation settings

How to use

Align each SMA male connector with the adapter's female ends, then gently engage and hand-tighten the coupling nut until secure. Avoid using excessive force or pliers to prevent damage to connector threads and ensure consistent electrical contact. Verify the connection visually and with test equipment as needed to confirm continuity and acceptable RF performance. For long-term installations, check and retighten connections periodically to maintain signal integrity.

Usage recommendations

Use this SMA female-to-female adapter for temporary joins or situations where minimal additional length is required. For critical RF paths or high-frequency applications, pay attention to connector quality and mating surface cleanliness; consider using a cable assembly matched for the system's frequency range to minimize insertion loss and reflection.
