Fixed Coaxial Attenuator

MCLI builds fixed coaxial attenuators in standard models from 2 watts to 50 watts, in values of 3 dB, 6 dB, 10 dB, 20 dB, and 30 dB, with specials up to 60 dB. Connector options cover SMA, BNC, TNC, 7/16 DIN, 2.92mm (K), and Type N, and high-power models extend the line to 500 watts. Standard models ship with M/F (male to female) connectors.

MCLI is an RF and microwave component manufacturer based in St. Petersburg, Florida, and every fixed attenuator in this line is designed, built, and tested in-house by our engineering team in the USA. These attenuators set signal levels and protect sensitive instrument inputs in defense, commercial, test, and research systems, and we supply government, commercial, and academic customers across the U.S. and internationally. With over 40 years in RF manufacturing, custom dB values and connector combinations built on request, a large stock inventory, and same-day shipping on in-stock models, MCLI keeps your build on schedule.
