The series FXA general purpose fixed attenuator consists of a waveguide section with a precisely cut resistive vane. It is available in nine waveguide bands from 18 to 170 GHz. The precision fixed attenuators are made using a rugged split block design. This attenuator can be used as a laboratory standard against which other instruments or components are calibrated.
