What are RF coaxial attenuators?
RF coaxial attenuators are passive components used to reduce the power of a high-frequency signal without distorting its waveform. Essential in RF testing, telecommunications, radar, instrumentation and industrial systems, they protect sensitive equipment, calibrate power levels and ensure proper impedance matching. Their coaxial design guarantees compatibility with standard connectors and professional RF setups.
How to choose the right RF attenuator
- Attenuation value (dB): select from 1 to 60 dB depending on the required power reduction.
- Operating frequency: choose models up to 27 GHz for microwave and advanced RF applications.
- Rated power: from 2W to over 100W depending on input power levels.
- Construction type: fixed attenuators for standard setups, variable attenuators for adjustable control.
