PE70A1044S

Overview

The Pasternack PE70A1044S is a push-button step attenuator featuring 50 ohm SMA female connectors on both sides. It provides an attenuation range of 0 to 90 dB with 1 dB resolution steps. The device operates from DC to 3 GHz and supports a maximum power rating of 5 watts.

Feature Summary

• Push-button mechanical interface for rapid attenuation adjustment
• High-resolution 1 dB step control across the full attenuation range
• Robust 5-watt continuous wave power handling capability

Applications

• Precision signal level calibration in test and measurement systems
• RF circuit characterization requiring variable signal reduction
• Telecommunications equipment testing and validation

Procurement Notes

Verify the specific suffix 'S' against official datasheets to confirm the 3 GHz frequency limit and 5-watt power rating. Ensure connector gender matches system requirements, as SMA female-to-female configurations are distinct from male variants. Cross-reference manufacturer documentation for exact attenuation accuracy specifications prior to integration.

Selection Notes

Select this model when precise 1 dB resolution is required up to 90 dB within a 3 GHz bandwidth. Consider the 5-watt power rating for high-power applications. Verify physical interface compatibility with existing SMA female ports. Evaluate alternative series if frequencies exceed 3 GHz or if different connector types are necessary.

Part Context

This component belongs to the Pasternack SMA 50 ohm step attenuator family. These devices are designed for precision signal attenuation in microwave systems. The series typically offers various attenuation ranges and power ratings, supporting frequencies up to 18 GHz in other models.

Replacement Considerations

The PE70A1044N is a related variant offering similar functionality but potentially differing in frequency range or power specifications. Verify technical parameters against original requirements before substitution.
