PE7040-20

Overview

The Pasternack PE7040-20 is a fixed RF attenuator designed for high-frequency applications. It provides a precise attenuation value of 20 dB with a frequency range extending up to 7.5 GHz. The device features 7/16 DIN male and female connectors, ensuring robust connectivity in test and measurement environments. Constructed with a black anodized aluminum heatsink body, it effectively dissipates heat during operation. The unit is rated for a maximum power handling capacity of 10 Watts at the stated attenuation level, making it suitable for demanding signal processing tasks.

Feature Summary

• Provides stable 20 dB attenuation across a wide frequency spectrum
• Utilizes durable 7/16 DIN connector interface for secure attachment
• Incorporates anodized aluminum heatsink body for thermal management

Applications

• RF signal testing and measurement setups
• Microwave system calibration procedures
• Signal level reduction in communication networks

Procurement Notes

Verify the specific connector gender configuration and power rating requirements against your system specifications before ordering. Confirm that the operating frequency does not exceed the 7.5 GHz limit. Ensure compatibility with existing 7/16 DIN infrastructure. Check manufacturer documentation for detailed environmental operating conditions and mechanical dimensions to guarantee proper integration into your assembly.

Selection Notes

Choose this model when a fixed 20 dB loss is required within the 7.5 GHz bandwidth. The 7/16 DIN interface suits applications needing high-power handling and reliable connections. Consider the 10 Watt power rating for systems generating significant thermal load. Evaluate space constraints due to the heatsink body design compared to smaller connector types like N-type or BNC.

Part Context

This component belongs to Pasternack's line of fixed microwave attenuators. It serves as a passive device to reduce signal amplitude without distortion. The product series typically includes various attenuation values and connector combinations. This specific variant focuses on mid-to-high frequency performance using industrial-grade materials for longevity and consistent electrical characteristics in professional laboratory settings.

Replacement Considerations

Direct substitutes must match the 20 dB attenuation, 7.5 GHz frequency range, and 7/16 DIN connector type. Verify equivalent power ratings of at least 10 Watts. Cross-reference impedance specifications to ensure 50 Ohm compatibility. Alternative models from other manufacturers may require adapter usage if connector interfaces differ.
