Coaxial adapter OEM CA-SM-SM — SMA male to SMA male

Coaxial adapter OEM CA-SM-SM — SMA male to SMA male is an inline RF connector designed to join two SMA-female coaxial cables or devices. The adapter preserves the coaxial signal path with a simple mechanical connection, providing continuity for RF and microwave signals in test setups, antenna systems, and equipment interconnections. Its compact, straight-through form factor makes it suitable for tight assemblies and temporary or permanent joins where SMA terminations are required.

Advantages

The SMA male-to-male adapter offers a reliable mechanical and electrical connection with minimal insertion loss when used within its intended frequency range. Its standard SMA interface ensures compatibility with a wide range of RF cables, antennas, and instruments. The inline design reduces the need for re-terminating cables and enables quick extension or coupling of SMA-equipped components. The small size and threaded coupling provide stable mating and resistance to casual disconnection.

Suitable for

• Extending an SMA-terminated coaxial cable by coupling two female SMA connectors
• Connecting RF test equipment and measurement devices with SMA interfaces
• Joining antennas or antenna cables in wireless installations and prototyping
• Temporary or semi-permanent links in lab benches, field testing, and troubleshooting

Key specifications

• Connector type: SMA male to SMA male (inline)
• Interface: threaded SMA coupling for secure mechanical connection
• Typical use: RF and microwave signal paths for coaxial cables
• Form factor: compact, straight-through adapter suitable for tight spaces
• Materials: conductive center contact with metallic outer body for shielding (standard SMA construction)

How to use

Align the SMA male threads of the adapter with the SMA-female jack on each cable or device, then carefully engage the threaded coupling by hand until finger-tight. Avoid cross-threading by ensuring straight alignment before turning. If needed, use a small torque wrench or appropriate tool to achieve a secure connection without over-tightening; follow the recommended torque for SMA connectors given by your cable or equipment manufacturer. Inspect connections for firm seating and confirm signal continuity through testing where applicable.

Usage recommendations

Use the adapter within the frequency and power limits appropriate for SMA connections; avoid exposing the adapter to moisture, excessive mechanical stress, or environments outside specified operating conditions for attached cables and equipment. For long-term or outdoor installations consider using weatherproofing or sealed connectors and verify that mating connectors are compatible and in good condition to maintain signal integrity.
