PE7053-20

Overview

The Pasternack PE7053-20 is a fixed coaxial attenuator designed for RF and microwave applications. It provides a nominal attenuation of 20 dB with a frequency range extending from DC to 18 GHz. The component utilizes TNC male-to-TNC female connectors for inline integration into transmission lines. Constructed with a black anodized aluminum heatsink body, it supports a power rating of up to 10 Watts at the specified attenuation value. This design ensures stable performance in high-frequency signal processing environments requiring precise signal reduction.

Feature Summary

• Fixed 20 dB attenuation value maintained across the operational bandwidth
• TNC connector interface facilitates direct inline circuit integration
• Anodized aluminum heatsink body enhances thermal dissipation capabilities

Applications

• RF signal level adjustment in communication systems
• Microwave test and measurement setups
• Signal conditioning in radar equipment

Procurement Notes

Verify that the required attenuation value matches the 20 dB specification exactly. Confirm that the system operates within the DC to 18 GHz frequency range. Ensure the application does not exceed the 10 Watt power rating. Check that TNC connectors are compatible with existing cable assemblies. Review RoHS compliance status if environmental regulations apply to the deployment.

Selection Notes

Select this model when a fixed 20 dB reduction is required without variable control. Consider the TNC interface compatibility against SMA or N-type alternatives. Evaluate the 10 Watt power handling against peak signal levels. Assess the need for an integrated heatsink versus external cooling solutions. Verify frequency requirements do not exceed the 18 GHz upper limit.

Part Context

This component belongs to the Pasternack PE7053 series of fixed attenuators. The series includes variants with different attenuation values such as 10 dB and 30 dB. These components share similar construction methods using resistive PI pad designs. The series targets applications requiring reliable signal attenuation in coaxial environments.

Replacement Considerations

Direct substitutes include other Pasternack models with identical 20 dB attenuation and TNC interfaces. Cross-brand replacements must match the 18 GHz frequency range and 10 Watt power rating. Connector type compatibility is critical for physical integration. Verify impedance matching remains at 50 Ohms for equivalent performance.
