PE7047-40

Overview

The Pasternack PE7047-40 is a fixed 40 dB attenuator featuring N Male to N Female connectors. It utilizes a resistive PI attenuator pad design within a passivated stainless steel heatsink body. The component operates at a maximum frequency of 3 GHz and supports a maximum operating temperature of +125 C. This coaxial 50 Ohm device provides precise signal attenuation for RF applications.

Feature Summary

• Fixed 40 dB attenuation value
• N Male to N Female connector configuration
• Passivated stainless steel heatsink body construction

Applications

• RF signal level reduction
• Impedance matching in coaxial systems
• Test and measurement setups

Procurement Notes

Verify the specific datasheet version for the PE7047-40 to confirm exact mechanical dimensions and material specifications. Ensure compatibility with system requirements regarding the 3 GHz frequency limit and 50 Ohm impedance. Cross-reference connector gender and attachment type to prevent installation errors in existing RF chains.

Selection Notes

Select this model when a fixed 40 dB attenuation is required between N-type connectors. The stainless steel body offers durability and thermal management capabilities suitable for environments up to +125 C. Consider the 3 GHz upper frequency limit to ensure performance integrity within the intended operational bandwidth.

Part Context

This part belongs to Pasternack's line of fixed coaxial attenuators. Similar models in the series include varying attenuation values such as 6, 7, 12, 20, and 30 dB, all sharing the N Male to N Female interface and stainless steel construction. The PE7047-40 specifically addresses high-attenuation needs within the UHF and lower microwave spectrum.

Replacement Considerations

Direct substitutes may include other manufacturers' N-type 40 dB fixed attenuators with similar power handling and frequency ratings. Verify that replacement parts maintain the 50 Ohm impedance and passivated stainless steel housing to ensure mechanical and electrical continuity.
