Procurement Notes

Verify component authenticity through authorized Infineon channels or certified distributors. Confirm the specific ordering suffix matches the required tape-and-reel quantity of 15,000 pieces per reel. Ensure handling precautions are observed due to electrostatic discharge sensitivity during storage and assembly processes.

Selection Notes

Select this component when designing circuits requiring a transition frequency of 9 GHz and a noise figure below 1.3 dB at 1.8 GHz. Verify that the 10 V collector-emitter voltage rating aligns with the circuit's supply requirements. Consider the TSLP-3-1 package dimensions for PCB layout constraints and thermal management needs.
