Attenuators are essential components used to reduce signal strength without significantly distorting the waveform. They are crucial in RF and microwave applications where control over signal amplitude is necessary to protect sensitive equipment or to match impedance. Attenuators can be fixed or variable and come in different configurations, such as coaxial and chip types.

By precisely controlling signal attenuation, these devices improve signal integrity and prevent damage to RF components. Attenuators are commonly used in communication systems, test and measurement equipment, and broadcasting systems, ensuring signal levels are kept within acceptable ranges.

Key manufacturers like Mini-Circuits, Keysight Technologies, and Pasternack offer high-performance Attenuators known for their precision and reliability. These companies provide a wide range of attenuators to meet the specific requirements of various RF applications.
