PE7391-10

Overview

The Pasternack PE7391-10 is a fixed RF attenuator designed for signal level reduction in coaxial systems. It provides a nominal attenuation of 10 dB with a frequency range extending from 0 Hz to 3 GHz. The device features SMA male-to-female connectors and is housed in an aluminum body with a black anodized finish. It is rated to handle up to 5 Watts of power at the stated attenuation value, ensuring reliable performance in microwave applications.

Feature Summary

• Fixed 10 dB attenuation value for precise signal control
• Broadband operation covering DC to 3 GHz frequencies
• SMA connector interface for standard coaxial integration
• Aluminum heatsink body for thermal management

Applications

• RF test and measurement setups
• Microwave communication systems
• Signal conditioning circuits
• Attenuation requirements in antenna feeds

Procurement Notes

Verify the specific datasheet version for exact VSWR and insertion loss tolerances before integration. Confirm that the SMA connector gender matches the system cabling requirements. Ensure the operating environment temperature remains within the component's specified limits to maintain the 5W power rating. Check for any RoHS compliance documentation if required by project specifications.

Selection Notes

Select this model when a fixed 10 dB reduction is required within the 3 GHz bandwidth. The aluminum construction supports higher power handling compared to plastic alternatives. Consider the physical size constraints as it includes a heatsink design. Verify that the SMA interface compatibility aligns with existing system connectors to avoid adapter usage.

Part Context

This component belongs to the Pasternack PE7391 series of fixed attenuators. Similar models include PE7391-6 (6 dB) and PE7391-20 (20 dB), offering different attenuation levels within the same form factor and frequency range. The series maintains consistent SMA connectivity and power ratings across variants.

Replacement Considerations

Direct substitutes may include other manufacturers' 10 dB SMA fixed attenuators rated for 3 GHz and 5W. Ensure replacement parts match the mechanical dimensions and connector torque specifications. Verify that alternative components meet the same electrical performance criteria for insertion loss and VSWR.
