Procurement Notes
Verify part status carefully as this component may be obsolete. Confirm package type and pinout compatibility with existing designs. Check for alternative sources if original manufacturing supply is discontinued. Ensure datasheet revisions match design requirements before procurement.
Selection Notes
Select this component for RF front-end designs requiring vector multiplication in cellular bands. Consider the integrated passive components for simplified PCB layout. Evaluate thermal performance within the 32-WFQFN package constraints. Verify frequency coverage matches specific network standards like GSM or UMTS.
Part Context
This device belongs to the Maxim Integrated RF portfolio, now part of Analog Devices. It serves as a specialized analog multiplier for wireless communication infrastructure. The integration of charge pumps and capacitors distinguishes it from discrete multiplier solutions, offering a compact form factor for mobile base stations and handsets.
Replacement Considerations
Check for direct cross-reference part numbers from Analog Devices. Since the part status is listed as obsolete, identify functional equivalents that support the same frequency range and package footprint. Verify electrical parameters against current available inventory.
