PE70A1045N

Overview

The PE70A1045N is a push-button step attenuator manufactured by Pasternack, designed for RF interconnect applications. It features N female connectors on both input and output sides with a characteristic impedance of 50 Ohms. The device provides an attenuation range from 0 to 90 dB with precise 1 dB step increments. It is rated for a maximum power handling capacity of 5 Watts and operates effectively within a frequency range extending up to 4 GHz. This component is suitable for high-precision signal control in test and measurement environments.

Feature Summary

• Push-button mechanical interface for discrete attenuation steps
• N male-to-female connector configuration ensuring robust RF connectivity
• High-resolution 1 dB step precision across the full attenuation range

Applications

• RF signal level adjustment in laboratory test setups
• Calibration of microwave measurement instruments
• Signal path attenuation in telecommunications equipment testing

Procurement Notes

Verify the specific connector gender configuration (N Female to N Female) against system requirements before ordering. Confirm that the 5 Watt power rating and 4 GHz frequency limit align with the operational parameters of the target application. Ensure compatibility with standard N-type mating hardware to maintain optimal VSWR performance during installation.

Selection Notes

Select this model when precise 1 dB resolution is required over a wide dynamic range up to 90 dB. Consider the physical size and weight constraints associated with N-type connectors compared to smaller form factors like SMA. Evaluate the need for manual push-button control versus remote-controlled alternatives if integration into automated systems is planned.

Part Context

This part belongs to the Pasternack PE70A series of RF variable attenuators. The series includes various models with different connector types, attenuation ranges, and power ratings. The PE70A1045N specifically utilizes N-type connectors, distinguishing it from SMA-based variants in the same family, offering higher power handling and durability for benchtop applications.

Replacement Considerations

Direct substitutes include other Pasternack models with similar specifications, such as the PE70A1041N which offers a 2 Watt rating instead of 5 Watts. Cross-brand replacements must match the N female-to-female interface, 50 Ohm impedance, and 4 GHz frequency limit to ensure functional equivalence without adapter usage.
