Waveguide Attenuators, High Power Fixed Precision

Variable Attenuators

MCLI variable and fixed attenuators positions reduce power signal without disrupting its waveform and have the ability to change attenuation values within a frequency range while maintaining low insertion loss and VSWR. Variable attenuations may be operated with a multi-turn screwdriver-slotted shaft, turns counting dial, knob control dial option, or direct read options. MCLI also offer flatness models in many broad and narrow frequency ranges.

Fixed attenuators can be used in the measuring of signals on pads to lower the amplitude balance to enable measurements, or to protect the measuring device from signal levels that could be damaging. MCLI Fixed attenuators are offered in many connector configurations and frequency ranges with low and high power solutions.
