Procurement Notes

Verify the specific ordering suffix against official documentation to confirm packaging details such as reel specifications or tape-and-reel quantities. Confirm that the AEC-Q101 qualification report aligns with project requirements. Ensure handling precautions are observed due to electrostatic discharge sensitivity. Check for any end-of-life status updates directly from the manufacturer before finalizing procurement plans.

Selection Notes

Select this component when designing circuits requiring dual isolated RF stages within a minimal footprint. Evaluate the thermal resistance characteristics against the expected power dissipation levels in the target application. Consider the specific biasing conditions required to achieve the stated noise figure and gain performance metrics at the operating frequency.
