| RF Attenuator |
Home > Attenuators |
| Attenuators are used in a wide variety of applications and can satisfy almost any
requirement where a reduction in power is needed. Attenuators are used to extend the
dynamic range of devices such as power meters and amplifiers, reduce signal levels to
detectors, match circuits and are used daily in lab applications to aid in product design.
Attenuators are also used to balance out transmission lines that otherwise would have
unequal signal levels. |

MECA offers a wide selection of attenuators designed to exceed commercial specifications. Standard attenuation values of 3, 6, 10, 20 and 30 dB are available from STOCK! Need a special value? Many of our attenuators are available in all values from 0 - 40 dB in 1 dB increments. Custom models with different attenuation values, power ratings, frequency ranges, connector styles and configurations or plating are also readily available in quantity. With immediate access to our Applications Engineers, you can choose the best product solutions for your specific needs.
Specifying Tip:
For best results when selecting an RF attenuator for a given connector style, make sure to consider the amount of power being absorbed and the acceptable level of reflection (VSWR) that can be tolerated over the operating frequency range.
