Procurement Notes

Verify the specific suffix LS6 against official Analog Devices documentation to confirm pinout, thermal characteristics, and RoHS compliance status. Ensure the procurement channel sources genuine components from authorized distributors or manufacturers to avoid counterfeit risks associated with RF MMICs. Cross-reference the datasheet revision date with the batch code to ensure technical accuracy.

Selection Notes

Select this component when designing systems requiring high output power and linearity in the 24-27 GHz band without complex external matching. Consider the single-supply requirement and thermal management needs for the 16-pin SMT package. Evaluate if the 26 dB gain meets system link budget requirements directly or if additional amplification stages are necessary.
