Procurement Notes

Verify authenticity through authorized channels as supply status may be restricted. Confirm RoHS compliance details directly with the manufacturer prior to integration. Ensure storage conditions meet moisture sensitivity requirements specified in the datasheet. Validate that the QFN-32 footprint matches the target PCB layout exactly. Review thermal dissipation capabilities against system power constraints.

Selection Notes

Select this component when designing circuits operating between 12 and 16 GHz that require high third-order intercept point alongside low noise figure. The fixed 23 dB gain suits applications needing significant signal amplification without additional stages. Consider the 5V supply requirement for power budget calculations. Evaluate the QFN-32 package size against available board space constraints.
