Attenuators
An RF Attenuator is a passive network designed to reduce the power of a signal by a specific amount (measured in Decibels, or dB) without significantly distorting its waveform. They act as the “volume control” for high-frequency signals, protecting sensitive equipment from being overwhelmed or damaged by high power levels.
