PE7025-20

Overview

The Pasternack PE7025-20 is a fixed bidirectional RF attenuator designed for in-line applications. It features BNC male to BNC female connectors and operates within a frequency range of DC to 2 GHz. The unit maintains a system impedance of 50 Ohms with a nominal attenuation value of 20 dB. It is rated for a maximum input power of 10 Watts at the specified attenuation level. The device utilizes a black anodized aluminum heatsink body for thermal management.

Feature Summary

• Fixed bidirectional attenuation design
• Black anodized aluminum heatsink body
• BNC male to BNC female connector configuration

Applications

• RF signal path attenuation
• Test and measurement equipment
• Microwave circuit integration

Procurement Notes

Verify that the required attenuation value matches the specific model designation, as the product line includes variants with different dB ratings such as 2 dB or 20 dB. Confirm the connector gender and interface type align with the system requirements. Ensure the operating frequency does not exceed the component's rated limit of 2 GHz. Check the power rating against the maximum expected signal levels in the application to prevent damage.

Selection Notes

Select this component when a precise 20 dB reduction is needed within the 2 GHz bandwidth. The BNC interface suits standard laboratory and industrial setups. Consider the physical size and mounting requirements due to the heatsink body. Verify compatibility with existing cable assemblies and adapters. Evaluate if the fixed attenuation meets the design constraints without requiring variable adjustment.
