Huber+Suhner 85177138 RF AttenuatorStraight 2 dBMaleFemale

This RF attenuator reduces signal amplitude within coaxial systems while maintaining impedance matching for test and measurement, automation and electronic assemblies. It is a straight inline device designed for low-power applications, connecting via an SMA male to SMA female Interface and suitable for use across a wide RF band up to microwave frequencies.

• 50Ω impedance for stable system matching and minimal reflections
• 2dB attenuation delivering predictable signal reduction for calibration
• Operates to 18GHz enabling high-frequency test and measurement
• Gold-plated contacts for consistent conductivity and corrosion resistance
• Passivated body for enhanced surface durability in varied environments
• Rated -55 to 125°C for reliable performance across temperature extremes

• Suitable for RF bench calibration in electronics laboratories
• Ideal for inline attenuation in automation control signal chains
• Used for level-setting in microwave component testing up to 18GHz
• Can be used with coaxial assemblies requiring SMA gender change and attenuation
• Used for system protection in sensitive receiver front-ends

It provides a male-to-female SMA connection enabling straightforward inline insertion without adaptors.

Copper contacts with gold plating maintain low contact resistance and resist wear that can affect signal integrity.

Yes, its construction supports continuous use at temperatures up to 125°C while remaining functional down to -55°C.

It conforms to RoHS and EU requirements for restricted substances in electronic components.
