PE7311-3

Overview

The Pasternack PE7311-3 is a 3 dB fixed attenuator module designed for RF applications up to 7.5 GHz. It features an N female connector on one side and a 7/16 DIN male connector on the other, providing directional signal attenuation. The component is rated for 50 Watts of power handling at its specified attenuation value and maintains a 50 Ohm impedance system. This configuration allows for precise signal level reduction in microwave circuits while ensuring compatibility between standard N-type and larger 7/16 DIN interfaces.

Feature Summary

• Provides fixed 3 dB attenuation for signal level control
• Supports frequency range up to 7.5 GHz
• Handles up to 50 Watts of RF power
• Features directional coupling characteristics

Applications

• RF test and measurement setups requiring signal reduction
• Microwave circuit design for power leveling
• Signal distribution systems needing attenuation modules
• Communication equipment testing environments

Procurement Notes

Verify the specific connector orientation and gender combination matches your system requirements, as this model uses mixed interface types (N Female to 7/16 DIN Male). Confirm that the 50 Watt power rating aligns with your operational peak power levels to prevent damage. Ensure the 7.5 GHz frequency limit covers your entire application bandwidth. Request the official datasheet from Pasternack or authorized distributors to validate electrical parameters before integration into critical RF infrastructure.

Selection Notes

Choose this model when a fixed 3 dB reduction is required between N-type and 7/16 DIN interfaces. It is suitable for applications demanding high power handling up to 50 Watts within the 7.5 GHz range. Consider alternative attenuation values if different signal reduction levels are needed. Ensure physical space constraints accommodate the module size. Verify that directional performance meets system isolation requirements compared to non-directional alternatives.

Part Context

This component belongs to Pasternack's line of RF and microwave attenuators, which include various fixed and variable options. The PE7311 series specifically addresses needs for directional attenuation with mixed connector configurations. These modules support broader system integration by bridging different connector standards while maintaining consistent 50 Ohm impedance across the operational bandwidth for minimal reflection.

Replacement Considerations

Direct substitutes may include other Pasternack models with identical 3 dB attenuation and similar power ratings but potentially different connector combinations. Verify that any replacement maintains the 7.5 GHz upper frequency limit and 50 Watt power handling capability. Check if the substitute offers compatible directional characteristics and physical mounting requirements for seamless integration.
