Fixed Attenuators
DC to 3 GHz
50 and 75 Ohm Models
Fixed Attenuators Photo

Our extensive line of fixed, coaxial attenuator models are available in a wide range of attenuation values and a choice of frequency ranges.
Connector combinations of many sorts can be provided, including same-sex and between series, which can eliminate the need for cables or adapters.

Our MA-50 series attenuators are frequency rated to 3.0 GHz, with MA-50A series operating up to 2.0 GHz.
MA-75A series attenuators are rated to 2.0 GHz, while our unique MA-75B series performs up to 3.0 GHz.
Available in Any attenuation value up to 40 dB. All are designed to provide accurate attenuation at modest cost.

To specify the required attenuation value, replace the 'X' in the model with the attenuation value in dB.
   Example: MA-50/6N specifies a 6 dB MA-50 with type N male/female connectors
                     MA-50A/23TM specifies an 23 dB MA-50A with TNC male/male connectors.

Between-series connector combinations and non-standard connectors are also available.
Consult the factory with your specific requirements.
