PE7051-1

Overview

The Pasternack PE7051-1 is a fixed attenuator module designed for RF applications. It features TNC male to TNC female connectors and operates within a frequency range of 0 Hz to 12.4 GHz. The component provides a precise attenuation value of 1 dB with a nominal impedance of 50 Ohms. It is rated for a maximum power handling capacity of 2 Watts. The housing is constructed from brass with a nickel finish, ensuring durability and consistent performance in high-frequency signal environments.

Feature Summary

• Provides stable 1 dB attenuation across a wide DC to 12.4 GHz bandwidth
• Features robust brass nickel body construction for reliable thermal and mechanical performance
• Utilizes standard TNC male-to-female interface for seamless integration

Applications

• RF signal level adjustment in test and measurement equipment
• Impedance matching and signal conditioning in communication systems
• Attenuation requirements in microwave circuit design

Procurement Notes

Verify the specific connector gender configuration and physical dimensions against system requirements before ordering. Confirm that the 2 Watt power rating aligns with the operational signal levels to prevent damage. Ensure the 50 Ohm impedance matches the surrounding circuitry to maintain signal integrity. Check for any specific environmental certifications if the application involves harsh conditions.

Selection Notes

Select this model when a precise 1 dB reduction is required at frequencies up to 12.4 GHz. Consider the TNC interface compatibility with existing cabling and fixtures. Evaluate the 2 Watt power handling capability against peak and average signal strengths. The brass nickel body offers a balance of cost-effectiveness and performance for general-purpose RF applications.

Part Context

This component belongs to the Pasternack line of fixed attenuators, which are essential passive devices for controlling signal strength. Fixed attenuators like the PE7051-1 provide constant loss values regardless of input power or frequency within their specified range. They are distinct from variable attenuators, offering simplicity and reliability for static signal management tasks in RF engineering.

Replacement Considerations

Direct substitutes must match the 1 dB attenuation value, 50 Ohm impedance, and TNC connector type. Verify that alternative models support the same 12.4 GHz frequency range and 2 Watt power rating. Ensure physical dimensions and mounting styles are compatible with the existing assembly to avoid redesign efforts.
