PE7380-40

Overview

The Pasternack PE7380-40 is a fixed 40 dB attenuator designed for high-frequency RF applications. It features a 50 Ohm impedance and operates from DC to 7.5 GHz. The unit utilizes a resistive PI attenuator pad design housed in a black anodized aluminum heatsink body, rated for up to 25 Watts of power handling. Connectors are 7/16 DIN female on both input and output sides, ensuring compatibility with standard coaxial systems.

Feature Summary

• Fixed 40 dB attenuation value provided by an inline resistive PI pad design
• Black anodized aluminum heatsink body for thermal management
• Dual 7/16 DIN female connectors for secure coaxial interfacing
• Operates across a wide frequency range from DC to 7.5 GHz

Applications

• RF signal level reduction in test and measurement setups
• Impedance matching in microwave communication systems
• Signal conditioning in radar equipment
• Attenuation in satellite ground station links

Procurement Notes

Verify the connector gender matches system requirements, as this model specifies female-to-female configuration. Confirm the operating frequency does not exceed 7.5 GHz and power levels remain within the 25 Watt rating. Check datasheet specifications for VSWR and insertion loss tolerances to ensure compliance with circuit design constraints before finalizing procurement.

Selection Notes

Select this component when a precise 40 dB attenuation is required at frequencies up to 7.5 GHz. The 7/16 DIN interface suits heavy-duty industrial or military environments. Ensure the host system supports the physical dimensions and mounting style of the heatsink body. Compare against other Pasternack models like PE7380-20 if lower attenuation values are needed.

Part Context

This part belongs to Pasternack's line of fixed coaxial attenuators. It is distinct from variable attenuators and adapters. The PE7380 series generally shares similar construction but varies in attenuation value and connector type. This specific model focuses on high-power handling and wideband performance using the robust 7/16 DIN interface standard.

Replacement Considerations

Direct substitutes include other 40 dB fixed attenuators with 7/16 DIN female connectors. Verify that replacement parts maintain the same 50 Ohm impedance and 7.5 GHz upper frequency limit. Cross-reference with Pasternack models offering identical power ratings and physical form factors to ensure mechanical compatibility.
