PE70A5001

Overview

The PE70A5001 is a 5-bit TTL-controlled programmable step attenuator manufactured by Pasternack. It operates within a frequency range of 100 MHz to 18 GHz and provides a total attenuation range of 0 dB to 30 dB. The device features a 5 dB step resolution, allowing for precise signal level adjustments. It utilizes a 2.92mm female connector interface on both input and output ports, ensuring compatibility with standard RF test equipment. The unit maintains a 50 Ohm impedance throughout its operation. Designed for inline module applications, it offers reliable performance in high-frequency environments requiring controlled signal attenuation.

Feature Summary

• TTL logic control interface for digital attenuation adjustment
• Programmable step attenuation design with fixed 5 dB increments
• Dual 2.92mm female connector configuration for direct inline integration

Applications

• RF signal path testing and characterization
• Automated test equipment (ATE) systems
• Telecommunications instrumentation calibration

Procurement Notes

Verify the specific datasheet version for the PE70A5001 to confirm current insertion loss specifications and TTL voltage requirements. Ensure that the receiving system supports the 2.92mm connector type and provides appropriate TTL control signals. Confirm that the operating environment temperature ranges align with the component's rated specifications before deployment.

Selection Notes

Select this model when a fixed 5 dB step resolution is sufficient for the application. It is suitable for systems requiring up to 30 dB of programmable attenuation within the 18 GHz bandwidth. Consider alternative models if finer step resolutions or different connector interfaces are required for the specific setup.

Part Context

This component belongs to Pasternack's series of RF variable attenuators designed for precision measurement applications. It serves as a critical element in signal chain management, providing repeatable attenuation steps controlled via digital logic. The 2.92mm interface ensures low VSWR and stable performance at microwave frequencies.

Replacement Considerations

PE70A5000: Offers 0.25 dB step resolution instead of 5 dB steps.
