PE7357-40

Overview

The PE7357-40 is a fixed 40 dB attenuator manufactured by Pasternack. It features an SMA male to SMA female interface configuration and utilizes a black anodized aluminum heatsink body. The component is designed as an in-line, resistive PI attenuator pad. It operates within a 50 Ohm impedance system and is rated for up to 25 Watts of power handling up to 18 GHz frequency range.

Feature Summary

• Incorporates a resistive PI attenuator pad design for signal attenuation
• Constructed with a black anodized aluminum heatsink body for thermal management
• Provides fixed 40 dB attenuation value

Applications

• RF signal level reduction in coaxial systems
• Test and measurement equipment signal conditioning
• Communication system power monitoring circuits

Procurement Notes

Verify the specific datasheet version for the PE7357-40 to confirm current manufacturing status and compliance details. Ensure that the SMA connector gender orientation matches the intended circuit board or cable assembly requirements. Confirm that the 25 Watt power rating aligns with the maximum expected signal levels in the application environment to prevent component damage.

Selection Notes

Select this component when a precise 40 dB attenuation is required at frequencies up to 18 GHz. The SMA interface suits applications needing compact coaxial connections. Consider the heatsink body for high-power environments where thermal dissipation is critical. Verify impedance matching to ensure compatibility with existing 50 Ohm system infrastructure without introducing reflection losses.
