Attenuator Axing SZU 3-00

The Axing SZU 3-00 is a 20 dB inline attenuator engineered for signal level control across a wide frequency band from 0.0001 to 2.4 GHz. Its compact, silver metal housing offers corrosion resistance and mechanical stability while supporting precise attenuation for telecommunications, broadcasting and general RF installations. The device is suitable for insertion between signal sources and receivers to reduce power, prevent overload and improve overall system linearity.

Advantages

The attenuator provides a fixed 20 dB reduction with minimal added noise and stable performance over the specified frequency range. The metal enclosure ensures reliable shielding and long-term durability in indoor and sheltered outdoor environments. Its broadband characteristics allow consistent attenuation for analog and digital signals, and the simple inline form factor supports quick integration into existing coaxial cable runs.

Suitable for

• Level matching between signal sources and receivers in telecom and broadcast systems
• Preventing receiver overload and distortion in RF distribution networks
• Testing and measurement setups that require a fixed attenuation step
• Reducing signal strength for equipment protection and calibration

Key specifications

• Attenuation: 20 dB (fixed)
• Frequency range: 0.0001 – 2.4 GHz
• Connector type: inline coaxial interface suitable for standard RF cable assemblies
• Housing: metal, silver finish for mechanical protection and electromagnetic shielding
• Operating environment: indoor and sheltered outdoor use (avoid direct exposure to heavy weather)

How to use

Install the attenuator inline between the signal source and the receiver using compatible coaxial connectors, ensuring firm, clean connections to minimize reflections. Confirm that the attenuation value and frequency range meet the system requirements before installation. After mounting, verify signal levels with appropriate test equipment and adjust system gain as needed to achieve the desired output without exceeding receiver input specifications.

Usage recommendations

For reliable results, keep connectors clean and tighten to the manufacturer’s recommended torque where applicable. Avoid repeated rapid mate/demate cycles to maintain connector integrity. Use the attenuator within its specified frequency and environmental ranges to ensure consistent attenuation and low insertion loss.
