Procurement Notes

Verify the specific suffix LC3B against official Analog Devices documentation to confirm package type and compliance status. Ensure compatibility with existing board layouts regarding the leadless SMT footprint. Confirm availability through authorized channels as distribution status may vary. Validate thermal requirements for the intended operating environment before finalizing procurement.

Selection Notes

Select this component for designs requiring precise x2 frequency multiplication in the K-band and above. Consider the 5 V supply requirement and 48 mA current draw for power budgeting. Evaluate the leadless package constraints for assembly processes. Compare performance metrics such as output power and harmonic rejection against system specifications to ensure adequate margin.

Part Context

This part belongs to the Hittite Microwave (now Analog Devices) portfolio of RF and microwave integrated circuits.
