Procurement Notes

Verify component authenticity by checking the manufacturer marking 'ABs' on the SOT343 package against official Infineon documentation. Confirm the part number suffix matches the specific reel configuration required for your assembly process. Ensure handling precautions are followed due to electrostatic discharge sensitivity.

Selection Notes

Select this component when designing for low voltage operation below 4.5 V and requiring high gain in the UHF to microwave range. Consider the thermal resistance of 250 K/W and the need for adequate heat sinking if operating near the maximum power dissipation limit. Verify that the required bias currents align with the specified DC characteristics for optimal noise and gain performance.
