Fluke RF Attenuator, 50Ω Impedance, 250–500MHz Frequency Range - 4119-50

This RF attenuator is a straight BNC male-to-female inline device designed to reduce signal amplitude in 50Ω systems across a mid‑band frequency range. It connects via a BNC plug to a BNC socket and is intended for use where controlled attenuation is required without altering impedance characteristics. The construction combines a nickel‑plated outer body with gold‑plated contacts seated on beryllium copper alloy and brass contact materials, enabling stable electrical contact in typical RF environments.

Features and Benefits:

• 50Ω nominal impedance maintains system matching
• Operates from 250 MHz to 500 MHz for mid‑band applications
• Gold‑plated contact reduces contact resistance and wear
• Nickel body rated to 102°C for elevated temperature tolerance
• Straight BNC male‑to‑female orientation simplifies inline connections

Applications

• Suitable for RF test benches covering 250 MHz-500 MHz
• Ideal for attenuating signals between BNC‑connected instruments
• Used with 50Ω transmission lines requiring impedance preservation
• Can be used for signal‑level adjustment in laboratory setups
• Used for temporary inline attenuation in field measurements

What connector types are present on the device?

It has a BNC plug on one end and a BNC socket on the other.

Which materials form the contact interface?

Contacts comprise gold plating over beryllium copper alloy and brass.

What temperature can the body withstand during operation?

The outer plating and construction are rated for a maximum operating temperature of 102°C.

What impedance should the attached system present for correct operation?

The attenuator is intended for use in systems with a 50Ω characteristic impedance.

What physical orientation does the attenuator use for cabling?

The device is supplied in a straight inline configuration for direct coupling of coaxial runs.
