PE7048-40

Overview

The Pasternack PE7048-40 is a fixed RF attenuator designed for high-power applications, featuring N-type connectors. It provides a precise attenuation value of 40 dB with a 50 Ohm impedance characteristic. The device operates across a frequency range from DC to 12.4 GHz and is rated for a maximum power handling capacity of 10 Watts at the stated attenuation level. Constructed with a black anodized aluminum heatsink body, it ensures thermal stability during continuous operation.

Feature Summary

• Fixed attenuation design providing consistent signal reduction
• High power handling capability suitable for demanding RF environments
• Robust construction utilizing an anodized aluminum heatsink body for effective thermal management

Applications

• RF test and measurement setups requiring precise signal level control
• Communication systems needing signal attenuation for linearity optimization
• Aerospace and defense electronics testing environments

Procurement Notes

Verify the specific model number against official Pasternack documentation to ensure accuracy. Confirm that the required attenuation value matches the 40 dB specification. Check connector gender compatibility for both input and output ports. Ensure the operating environment does not exceed the 10 Watt power rating or 12.4 GHz frequency limit defined in the datasheet.

Selection Notes

Select this component when a fixed, high-power attenuation solution is required within the N-type connector ecosystem. Consider the 10 Watt power rating and 12.4 GHz bandwidth as critical constraints. Evaluate thermal requirements based on the heatsink design. Compare against variable attenuators if adjustable attenuation is needed instead of a fixed value.

Part Context

This part belongs to the Pasternack PE7048 series of fixed microwave attenuators. The series offers various attenuation values ranging from low to high dB levels, all sharing similar N-type connector interfaces and power ratings. This specific model represents the higher attenuation end of the standard lineup, maintaining consistency in form factor and performance characteristics across the family.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with existing fixtures before considering alternative manufacturers. Ensure any replacement maintains the 50 Ohm impedance and N-type interface specifications.
