PE7357-3

Overview

The Pasternack PE7357-3 is a fixed RF attenuator designed for high-frequency applications. It provides a nominal attenuation of 3 dB with an operating frequency range from 0 Hz to 18 GHz. The device features SMA male-to-female connectors and utilizes a black anodized aluminum heatsink body for thermal management. It is rated to handle up to 25 Watts of power at the stated attenuation value within its specified frequency band.

Feature Summary

• Provides precise 3 dB signal attenuation across a wide bandwidth extending to 18 GHz
• Constructed with a black anodized aluminum heatsink body for effective thermal dissipation
• Equipped with SMA male-to-female connectors for standard coaxial integration

Applications

• Microwave signal conditioning in test and measurement equipment
• RF circuit protection and level adjustment in communication systems
• Signal attenuation in radar and electronic warfare applications

Procurement Notes

Verify the specific datasheet version for the PE7357-3 to confirm exact electrical tolerances and mechanical dimensions. Ensure compatibility with SMA connector standards in your system design. Check for any RoHS compliance documentation if required by your manufacturing specifications. Confirm the power rating applies to the entire 0-18 GHz range as stated in official literature.

Selection Notes

Select this component when a fixed 3 dB reduction is required in systems operating up to 18 GHz. The 25 Watt power rating makes it suitable for moderate power levels. The SMA interface ensures broad compatibility with existing RF infrastructure. Consider the heatsink body for applications requiring passive thermal management without active cooling.

Part Context

This part belongs to Pasternack's line of fixed RF attenuators, which are essential components for controlling signal strength in microwave circuits. These devices are typically used to match impedance levels, protect sensitive downstream components from high power, or adjust signal levels for accurate measurement. The series offers various attenuation values and connector types to suit different RF system requirements.

Replacement Considerations

Compatible substitutes include other 3 dB SMA fixed attenuators rated for 18 GHz and similar power handling, such as the PE7357-3 from alternative manufacturers or equivalent models within the same family ensuring identical connector gender and frequency response.
