Attenuators

Attenuators are in stock with same-day shipping at Mouser from leading manufacturers. Mouser is an authorized distributor for many attenuator manufacturers including Analog Devices, MACOM, Mini-Circuits, pSemi, Qorvo, Skyworks & more.

Attenuators are passive electronic components designed to reduce signal power levels without significantly distorting the waveform being transmitted. They provide controlled signal reduction to help optimize signal strength, protect sensitive circuits, improve impedance matching, and maintain system performance across a wide range of electronic and RF applications. These devices are commonly used where precise signal level management is required to ensure reliable operation and measurement accuracy.

Types: The most common attenuator types include fixed attenuators, variable attenuators, programmable attenuators, RF attenuators, coaxial attenuators, chip attenuators, step attenuators, and high-power attenuators, each designed for specific frequency ranges, power levels, and signal control requirements.

Applications: Attenuators are widely used in wireless communication systems, test and measurement equipment, RF and microwave platforms, broadcast infrastructure, network equipment, aerospace systems, and signal conditioning applications to control and optimize signal levels.

Selection requirements: To choose attenuators, evaluate attenuation value, frequency range, power handling capability, impedance, insertion loss characteristics, accuracy, connector or package type, environmental durability, and suitability for the intended electrical and operating conditions.
