Coaxial cable SMA-W to SMA-W H155, 0.8 m length, no brand

Coaxial cable SMA-W to SMA-W H155, 0.8 m length is a short RF interconnect designed for devices with SMA-W male interfaces. The cable uses H155 dielectric construction to provide predictable electrical performance in the VHF/UHF and microwave ranges commonly used in laboratory testing, antenna connections and short patching applications. Its compact 0.8 m length reduces signal loss and cable bulk in bench setups and field installations while maintaining a consistent impedance for reliable RF transmission.

Advantages

The H155 dielectric design delivers stable characteristic impedance and controlled attenuation over the intended frequency range, ensuring consistent signal transfer between SMA-W terminated ports. The SMA-W male to SMA-W male connectors provide secure mechanical mating and repeatable RF contact. The short 0.8 m length minimizes insertion loss compared with longer leads and keeps cable routing tidy in constrained spaces.

Suitable for

• Lab test setups and measurement rigs using SMA-W interfaces
• Antenna connections for short runs where H155 characteristics are specified
• RF patching between equipment in bench and field environments
• Prototyping and temporary interconnects in wireless system development

Key specifications

• Cable type: coaxial with H155 dielectric construction
• Connector type: SMA-W male to SMA-W male
• Length: 0.8 m
• Characteristic impedance: nominal 50 ohm
• Typical use: RF signal transmission for VHF/UHF and microwave applications

How to use

Connect each SMA-W male connector to the corresponding SMA-W female port on your instruments, antennas or RF modules. Ensure connectors are aligned and hand-tightened to avoid over-torquing; use a torque wrench only if specified by the equipment manufacturer. Route the cable to avoid sharp bends and mechanical strain on the connectors. For measurement accuracy, keep the cable as short as practical and avoid running it parallel to high-power lines that could induce interference.

Usage recommendations

Inspect connectors for damage before use and keep mating surfaces clean and free of debris. Store the cable loosely coiled to prevent kinks and preserve dielectric integrity. For critical measurement or high-frequency applications, verify insertion loss and return loss with appropriate test equipment and replace the cable if performance degrades.
