PE7211-20

Overview

The Pasternack PE7211-20 is a fixed RF attenuator designed for high-power applications. It provides an attenuation value of 20dB with a frequency range spanning from 0 Hz to 6 GHz. The component operates at a power rating of 100 Watts and maintains a system impedance of 50 Ohms. This inline coaxial device utilizes a resistive PI attenuator pad design, ensuring stable signal reduction across its specified bandwidth while handling significant power loads in electronic test and measurement setups.

Feature Summary

• Fixed 20dB attenuation level
• High power handling capability up to 100W
• Wideband operation from DC to 6 GHz
• Inline coaxial resistive PI pad design

Applications

• RF signal level control in test equipment
• Power amplifier output matching
• Signal generator protection circuits
• Communication system attenuation stages

Procurement Notes

Verify the specific connector interface type (e.g., 7/16 DIN) against your system requirements, as datasheet details may vary by revision. Confirm that the 100W power rating aligns with your thermal management capabilities. Ensure the 50 Ohm impedance matches your existing transmission line infrastructure to prevent signal reflections and maintain system integrity during procurement.

Selection Notes

Select this model when a precise 20dB reduction is required within a 6 GHz bandwidth. Consider the 100W power rating for high-energy applications where standard attenuators might fail. The DC-to-6 GHz range makes it suitable for broadband testing scenarios. Verify compatibility with your specific connector types and mounting configurations before finalizing the selection for your RF chain.

Part Context

This component belongs to Pasternack's series of fixed RF attenuators. These devices are engineered for reliable performance in demanding radio frequency environments. The PE7211-20 specifically addresses needs for substantial power handling alongside precise attenuation values. It serves as a critical passive component for managing signal strength in complex electronic systems without introducing significant distortion or noise.

Replacement Considerations

Direct substitutes include other 20dB fixed attenuators from Pasternack with compatible interfaces. Models like PE7211-30 offer different attenuation levels but share similar construction principles. When replacing, ensure the new part matches the 50 Ohm impedance and 100W power rating. Verify that the frequency range covers the operational spectrum of the original application to maintain system performance.
