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.
