Coaxial Fixed Attenuators

Coaxial Fixed Attenuators

Coax Attenuators From 2 Watts To 50 Watts

ATM manufactures a wide selection of high quality Fixed Attenuators ranging from 2 watt to 50 watt models in standard dB values of 3db, 6db, 10db, 20db, 30db attenuators, and specials of up to 60dB for  SMA or Type-N. In addition to our standard line of coaxial attenuators ATM manufactures many special High Power models up to 500 watts.

Standard coaxial attenuators are supplied with M/F connectors. Other connectors supplied on request.  Consult factory for details.  Please call us with your requirements and discuss your requirements for coaxial attenuators with one of our design engineers.
