PE7391-30

Overview

The Pasternack PE7391-30 is a fixed RF attenuator designed for signal reduction in coaxial systems. It features SMA male to SMA female connectors and operates within a frequency range of 0 Hz to 3 GHz. The unit provides a nominal attenuation of 30 dB with a maximum power rating of 5 Watts. Constructed with a black anodized aluminum heatsink body, it ensures thermal stability during operation. The device maintains a characteristic impedance of 50 Ohms and exhibits a Voltage Standing Wave Ratio (VSWR) of 1.35:1, ensuring minimal signal reflection across its operational bandwidth.

Feature Summary

• Fixed 30 dB attenuation capability for precise signal level control
• SMA male-to-female interface for standard coaxial integration
• Black anodized aluminum heatsink body for thermal management
• Rated for 5 Watts power handling up to 3 GHz

Applications

• RF test and measurement setups requiring signal reduction
• Communication system signal conditioning
• Antenna feed line attenuation
• Laboratory equipment interconnects

Procurement Notes

Verify the specific connector gender configuration matches the application requirements before purchase. Confirm that the 5 Watt power rating is sufficient for the intended operating conditions. Ensure the SMA interface compatibility with existing cabling infrastructure. Check for any specific environmental ratings if outdoor or harsh condition usage is planned. Review datasheet specifications for VSWR limits to ensure signal integrity compliance.

Selection Notes

Select this model when a fixed 30 dB reduction is required at frequencies up to 3 GHz. Choose based on the need for SMA connectivity and 50 Ohm impedance matching. Consider the aluminum heatsink design for applications where passive thermal dissipation is necessary. Evaluate against variable attenuators if adjustable levels are needed instead.

Part Context

This component belongs to Pasternack's series of fixed RF attenuators. It is part of a family offering various attenuation values using similar SMA connector interfaces. The product line focuses on providing reliable signal attenuation solutions for microwave and radio frequency applications. Similar models may offer different attenuation levels or connector types while maintaining comparable construction standards.

Replacement Considerations

Direct substitutes include other 30 dB fixed attenuators with SMA male/female connectors and 50 Ohm impedance. Verify that replacement units support the same 3 GHz frequency range and 5 Watt power rating. Ensure physical dimensions and mounting requirements match the existing setup. Cross-reference VSWR specifications to maintain signal performance levels.
