Telegärtner SMA útlmový člen konektor samec na konektor samica, 20 dB, 2 W, 3 GHz (J01156A0041)

RF engineers and technicians working in test and measurement setups often need to reduce signal levels without introducing reflections. The Telegärtner SMA attenuator provides a fixed 20 dB attenuation in a compact inline package, making it a practical choice for bench testing, prototype validation, and system calibration where controlled signal reduction is required.

Key specifications

• Attenuation: 20 dB
• Frequency range: DC to 3 GHz
• Power handling: 2 W
• Impedance: 50 Ohm
• Connector: SMA male to SMA female
• VSWR: < 1.2:1
• Operating temperature: -55 °C to +125 °C
• Body material: brass, nickel plated
• Center contact: gold plated brass / beryllium copper
• Insulator: PTFE

Why choose it

The attenuator’s 50 Ohm impedance and low VSWR help maintain signal integrity across its operating band. Its SMA male-to-female configuration allows direct insertion into existing RF paths without additional adapters, and the 2 W power rating accommodates a wide range of test signals.

Ideal use cases

• RF and microwave test benches
• Signal level adjustment in measurement setups
• Protection of sensitive receiver inputs
• Calibration of RF equipment

Good to know

The attenuator is bi-directional, so it can be installed in either orientation. Its nickel-plated brass body and gold-plated contacts provide reliable performance in demanding laboratory and production environments.
