PE7311-20

Overview

The Pasternack PE7311-20 is a fixed attenuator module providing 20 dB attenuation. It operates from 0 Hz to 7.5 GHz with a 50 Ohm impedance. The device handles up to 50 Watts of power at the stated attenuation value. It features an N Female input and a 7/16 DIN Male output connector.

Feature Summary

• Directional signal attenuation capability
• High power handling capacity of 50 Watts
• Broadband frequency operation up to 7.5 GHz
• Anodized aluminum heat sink construction

Applications

• RF test and measurement setups
• Signal level reduction in microwave systems
• Protection of sensitive receiver inputs
• Calibration equipment integration

Procurement Notes

Verify the specific connector gender configuration matches the system requirement, as this model specifies N Female to 7/16 DIN Male. Confirm that the 50 Watt power rating aligns with the maximum expected signal levels in the application circuit to ensure safe operation within thermal limits.

Selection Notes

Select this component when a precise 20 dB reduction is required across a wide bandwidth extending to 7.5 GHz. Ensure the interface between N Female and 7/16 DIN Male connectors is compatible with the existing cabling infrastructure. Consider the physical size of the heat sink for enclosure space planning.

Part Context

This part belongs to Pasternack's line of RF and microwave components, specifically designed for signal conditioning. Fixed attenuators like the PE7311-20 are essential for maintaining signal integrity by preventing overload in downstream active components such as amplifiers or mixers.

Replacement Considerations

PE7316-20: Identical electrical specifications but utilizes 7/16 DIN Female connectors on both ends instead of the mixed N Female to 7/16 DIN Male configuration found in the PE7311-20.
