Procurement Notes

Verify availability status directly with authorized distributors or the manufacturer, as supply constraints may apply. Confirm RoHS compliance details and moisture sensitivity levels prior to ordering. Ensure that the specific suffix matches the required packaging configuration for your assembly process. Cross-reference the datasheet specifications against your design requirements to confirm compatibility with existing circuit architectures and thermal management solutions.

Selection Notes

Select this component when designing circuits requiring broadband amplification beyond standard narrowband limits. Consider the 10 V to 15 V supply requirement and associated power dissipation of 8.4 W for adequate thermal design. Evaluate the 12.5 dB gain and 5 dB noise figure against system link budget requirements. Ensure the LFCSP-32 package footprint fits within the PCB layout constraints and supports the necessary biasing network for stable operation at high frequencies.
