Procurement Notes

Verify component authenticity through authorized Analog Devices channels or certified distributors. Confirm the specific suffix 'TR' indicates reel packaging when sourcing. Check current availability status as supply may be restricted. Ensure handling procedures comply with moisture sensitivity levels defined in the datasheet. Validate that the received part matches the exact model number to avoid functional mismatches.

Selection Notes

Select this component when a wide bandwidth up to 18 GHz is required for frequency division. Consider the InGaP HBT process for superior high-frequency characteristics compared to standard silicon alternatives. Evaluate the 96 mA current consumption against system power budgets. Ensure the design accommodates the QFN-16 thermal pad requirements for adequate heat dissipation during continuous operation.
