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 3 dB Fixed Attenuator PE7041-3 is rated to 25 Watts and operates from DC to 7.5 GHz.

The versatile coaxial package uses 7/16 DIN male to 7/16 DIN 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.
