Procurement Notes

Verify the specific ordering suffix to ensure compatibility with required packaging and tape-and-reel specifications. Confirm RoHS compliance status as indicated in official documentation. Cross-reference the manufacturer's latest datasheet for any updates on pin configurations or recommended operating conditions prior to procurement.

Selection Notes

Select this component when precise digital attenuation steps are required in the 50 MHz to 3 GHz range. Consider its high linearity and compact form factor for space-constrained designs. Ensure the control interface matches the system's logic levels and that the thermal requirements align with the application environment.

Part Context

This part belongs to the PE43xxx series of digital step attenuators from pSemi, a Murata company. The series leverages proprietary HaRP™ technology to deliver superior RF performance compared to traditional silicon-based solutions. These components are designed for integration into modern wireless infrastructure and portable devices.

Replacement Considerations

Check for direct substitutes within the PE43xxx family that offer similar attenuation ranges and control interfaces. Verify pin-to-pin compatibility and electrical parameter equivalence before substitution. Consult official cross-reference guides for validated alternatives.
