PE7161-30

Overview

The Pasternack PE7161-30 is a 30 dB fixed attenuator featuring SMA male to SMA female connectors. It utilizes a brass tri-metal body and is rated for 1 Watt maximum input power up to 2 GHz. The device maintains a 50 Ohm impedance with an attenuation accuracy of ±1.5 dB. Maximum VSWR is 1.2:1 across the DC to 2 GHz range. Operating temperature spans -20°C to +85°C. Physical dimensions are 0.98 inches in length and 0.312 inches in width.

Feature Summary

• Fixed bidirectional attenuation design
• SMA male to SMA female connector configuration
• Brass tri-metal body construction

Applications

• RF signal level reduction
• Impedance matching in microwave circuits
• Test and measurement equipment

Procurement Notes

Verify the specific datasheet version for the PE7161-30 model, as documentation may reference similar series parts like PE7161-40 or PE7161-10. Confirm that the 2 GHz frequency rating and 1 Watt power handling align with your system requirements. Ensure the SMA connector gender matches your interconnect needs. Check for any specific environmental ratings beyond the standard operating temperature range if required for your application.

Selection Notes

Select this component when a precise 30 dB attenuation value is required within a 50 Ohm system up to 2 GHz. The SMA interface ensures compatibility with standard coaxial cables and fixtures. Consider the 1 Watt power limit and brass body material for thermal and mechanical suitability. Compare against other attenuation values in the PE7161 series if different signal levels are needed.

Part Context

This part belongs to the Pasternack PE7161 series of fixed attenuators. Similar models include the PE7161-5 (5 dB), PE7161-10 (10 dB), and PE7161-40 (40 dB). These components share common design features such as the SMA connector type and brass tri-metal body, differing primarily in their attenuation values and potentially frequency ranges.

Replacement Considerations

Direct substitutes include other PE7161 series models with adjusted attenuation values, such as PE7161-10 or PE7161-40, if the specific 30 dB value is not critical. Cross-reference with other manufacturers' SMA fixed attenuators meeting the 50 Ohm, 1 Watt, and 2 GHz specifications.
