PE70A1041B

Overview

The Pasternack PE70A1041B is a coaxial RF step attenuator designed for precision signal control in microwave applications. It provides an attenuation range of 0 to 90 dB with 1 dB resolution steps, operating from DC to 3 GHz. The device features N female connectors on both ports and maintains a 50-ohm impedance. Rated for 2 watts of power handling, it ensures low insertion loss and a maximum VSWR of 1.5:1. This push-button controlled module is suitable for test instrumentation and telecommunications equipment requiring reliable attenuation.

Feature Summary

• Push-button controlled step attenuation mechanism
• Wide dynamic range from 0 to 90 dB
• Low voltage standing wave ratio (VSWR) performance
• Robust 2-watt power handling capability

Applications

• General-purpose RF test and measurement instrumentation
• Telecommunications system signal conditioning
• Laboratory calibration setups

Procurement Notes

Verify the specific connector gender and interface type matches your system requirements before ordering. Confirm that the frequency range up to 3 GHz aligns with your operational bandwidth. Ensure the 2-watt power rating is sufficient for your signal levels. Check for any specific environmental or mounting constraints associated with the module form factor.

Selection Notes

Select this model when precise 1 dB step adjustments are required within the 0-90 dB range. It is appropriate for systems operating below 3 GHz where N-type connectivity is standard. Consider the power rating and VSWR specifications to ensure compatibility with sensitive downstream components. Evaluate if push-button control meets the automation needs of the application.

Part Context

This component belongs to the Pasternack RF Attenuators series, specifically the PE70A family of coaxial step attenuators. These devices are engineered for high-reliability performance in microwave and RF environments. The series typically offers various attenuation ranges and connector options to support diverse testing and signal processing requirements across industrial and commercial sectors.

Replacement Considerations

Compatible substitutes include models such as PE70A1041N (N Female) or PE70A1041B variants with similar electrical characteristics. Verify that replacement units maintain the same 0-90 dB range, 1 dB step resolution, and 50-ohm impedance. Ensure the frequency response and power handling capabilities match or exceed the original specifications.
