Coaxial RF Cable SMA male to SMA female H155 0.2 m — No name

Coaxial RF cable SMA male to SMA female H155 0.2 m is a short, flexible jumper designed to connect devices with SMA interfaces. The H155 dielectric and coaxial construction provide consistent impedance for RF signal transmission over a 0.2 m length, making this cable suitable for compact setups where minimal insertion loss and reliable connector mating are required. The cable is intended for low-loss connections between test instruments, antennas, and RF modules in laboratory, workshop, and installation environments.

Advantages

This SMA male to SMA female cable offers a compact 0.2 m length that reduces clutter and signal reflections in short-run applications. The H155 dielectric construction contributes to predictable characteristic impedance, helping maintain signal integrity at high frequencies. Fitted SMA connectors provide secure mechanical mating and repeatable electrical contact for frequent connection and disconnection.

Suitable for

• Connecting RF test equipment and measurement instruments
• Antenna feed lines for compact installations
• Short patch leads between RF modules and development boards
• Laboratory setups and bench testing where a short jumper is needed

Key specifications

• Connector types: SMA male to SMA female
• Cable type: H155 coaxial construction
• Length: 0.2 m
• Impedance: 50 Ω (typical for SMA/H155 assemblies)
• Application: RF signal transmission for high-frequency connections

How to use

Ensure both mating connectors on the devices are clean and free of debris before making the connection. Align the SMA male pin with the female receptacle and hand-tighten the coupling nut; avoid overtightening to prevent damage to the connector. Keep cable bends larger than the minimum bend radius recommended for H155-type coax to avoid increased loss or mechanical stress. For test or measurement use, route the cable to minimize proximity to noise sources and avoid sharp kinks.

Usage recommendations

Use this short SMA male to SMA female H155 cable where a reliable, low-loss jumper is needed over a 0.2 m distance. Store the cable coiled without tight loops, inspect connectors periodically for wear, and replace if threads or center contacts show signs of damage to maintain consistent RF performance.
