Description
Pasternack carries a wide range of fixed attenuators with a broad selection of attenuation levels, frequency ranges, and power
dissipation ranges. RF microwave attenuators (also known as RF pads) lower the amplitude of a signal (attenuate) a known
amount and can be used in a wide variety of applications. These attenuator pads are used when a signal needs to be reduced
to protect measurement equipment or other circuitry, to extend the range of power meters and amplifiers, and to impedance
match circuits by reducing the VSWR seen by adjacent components. RF attenuators can prevent signal overload in amplifiers,
receivers and detectors, adjusting the signal level to a range that is optimal.

Few RF components are as commonly used as fixed coaxial attenuators, and Pasternack carries one of the largest in-stock
varieties and ships them same day. The 20 dB Fixed Attenuator PE7389-20 is rated to 50 Watts and operates from DC to 3
GHz. The versatile coaxial package uses N male to N female connectors and is also REACH and RoHS compliant. The Black
Anodized Aluminum Heatsink body allows for efficient heat dissipation under high power usage conditions.
