PE7221-3

Overview

The Pasternack PE7221-3 is a fixed RF attenuator module designed for in-line signal reduction. It provides a precise attenuation value of 3 dB across a frequency range of 0 Hz to 6 GHz. The component features SMA female-to-SMA male connectors and operates with a characteristic impedance of 50 Ohms. It is rated for a maximum power handling capacity of 100 Watts at the stated attenuation level, ensuring reliable performance in high-power microwave applications.

Feature Summary

• Provides fixed 3 dB signal attenuation
• Operates from DC to 6 GHz
• Supports 100 Watt power handling
• Features SMA female to male interface

Applications

• Microwave test and measurement setups
• RF signal path power reduction
• Communication system calibration
• Laboratory equipment integration

Procurement Notes

Verify the specific connector gender configuration matches the design requirements, as SMA interfaces are directional. Confirm that the 100 Watt power rating aligns with the operational thermal conditions of the target application. Ensure the 6 GHz frequency limit covers the entire bandwidth of the intended signal spectrum without degradation.

Selection Notes

Select this model when a fixed 3 dB reduction is required within the 0-6 GHz band. Consider the 50 Ohm impedance match for standard RF systems. Evaluate the physical form factor against available space constraints. Compare against variable attenuators if adjustable loss is needed instead of a fixed value.

Part Context

This component belongs to the Pasternack attenuator product line, which includes various fixed and variable types. It utilizes standard SMA connectors common in RF engineering. The module format allows for direct integration into coaxial chains. It serves as a passive component for managing signal levels in microwave circuits.

Replacement Considerations

Substitute with other 3 dB fixed attenuators from Pasternack or third-party manufacturers offering SMA interfaces. Ensure the replacement supports the same 50 Ohm impedance and 6 GHz frequency range. Verify equivalent power handling capabilities to maintain system safety and performance standards.
