PE7311-30

Overview

The PE7311-30 is a fixed RF attenuator module manufactured by Pasternack. It provides a nominal attenuation of 30 dB with a frequency range from 0 Hz to 7.5 GHz. The device operates at a characteristic impedance of 50 Ohms and supports a maximum power handling capacity of 50 Watts. The connector configuration consists of an N Female input and a 7/16 DIN Male output, designed for reliable signal reduction in high-power microwave applications.

Feature Summary

• Provides precise 30 dB signal attenuation across a wide DC to 7.5 GHz bandwidth
• Supports high power handling up to 50 Watts for robust performance
• Features mixed interface connectors combining N Female and 7/16 DIN Male types

Applications

• High-power microwave test and measurement setups
• Signal level reduction in RF transmission lines
• Protection of sensitive receiver components from excessive input power

Procurement Notes

Verify the specific datasheet version for detailed electrical tolerances and environmental operating limits before integration. Confirm that the mixed connector interface (N Female to 7/16 DIN Male) aligns with existing system hardware requirements. Ensure the 50 Watt power rating exceeds the maximum expected signal levels in the application circuit to prevent component damage.

Selection Notes

Select this model when a fixed 30 dB attenuation value is required within the 0 Hz to 7.5 GHz spectrum. The 50 Watt power rating distinguishes it from lower-power variants suitable for standard communication links. The specific combination of N Female and 7/16 DIN Male connectors dictates its compatibility with legacy or specialized RF infrastructure requiring this transition.

Part Context

This component belongs to the Pasternack series of fixed RF attenuators. It serves as a passive linear device used to reduce signal amplitude without distortion. The module design integrates internal resistive elements housed within a shielded enclosure to maintain impedance stability and minimize external interference during operation.

Replacement Considerations

Public confirmed substitute part numbers include PE7311-40 and PE7311-50. These alternatives offer different attenuation values while maintaining similar power and frequency specifications.
