Procurement Notes

Verify manufacturer documentation for current availability as Harris Corporation assets have changed ownership. Confirm package variant (SSOP vs QSOP) matches design requirements. Check for obsolescence status due to corporate restructuring history.

Selection Notes

Select this component for legacy cellular infrastructure requiring integrated downconversion. Ensure system design accommodates the specific 869-895MHz input range. Verify thermal management for the 28-lead plastic package.

Part Context

Harris Corporation was a major electronics manufacturer before its semiconductor division was acquired by Intersil, which later merged with Renesas. This part represents legacy RF technology from that era.

Replacement Considerations

No public confirmed substitute part numbers are available in standard catalogs. Legacy support may require checking Renesas or Intersil archives for direct equivalents.
