PE7053-40

Overview

The Pasternack PE7053-40 is a fixed coaxial attenuator featuring TNC male to TNC female connectors. It provides a precise attenuation value of 40 dB across a frequency range of 0 Hz to 18 GHz. The device is rated for a maximum power handling capacity of 10 Watts at the specified attenuation level. Constructed with a black anodized aluminum heatsink body, it ensures thermal stability during operation. This component utilizes an in-line resistive PI pad design to maintain consistent impedance characteristics.

Feature Summary

• In-line resistive PI pad design for stable signal attenuation
• Black anodized aluminum heatsink body for thermal management
• TNC male to TNC female connector configuration

Applications

• RF and microwave test measurement setups
• Signal level reduction in communication systems
• Impedance matching in 50 Ohm transmission lines

Procurement Notes

Verify the specific datasheet version for updated electrical tolerances and mechanical dimensions before integration. Confirm that the operating environment remains within the 10 Watt power rating limit to prevent component damage. Ensure connector compatibility with existing TNC interfaces in the assembly. Check for RoHS compliance documentation if required by project specifications.

Selection Notes

Select this model when a fixed 40 dB attenuation is required up to 18 GHz. The TNC interface suits applications needing robust threaded connections. The aluminum heatsink design supports higher power dissipation compared to standard plastic-bodied attenuators. Consider the physical size constraints of the heatsink body during layout planning.

Part Context
