Passive devices are one of the two major categories in the field of RF microwave, passive devices include passive filters, power dividers and other microwave components that can work without external power supply.

Fixed Attenuators are electronic devices used to reduce the power level of a signal by a fixed amount with minimal distortion. They are designed to have a fixed and unchangeable attenuation. Fixed attenuators assist in preventing excess signals in devices or in reducing the effects of improper input/output terminations of oscillators, amplifiers etc., by controlling the power levels of the devices to a given value or range.
