Procurement Notes

Verify component authenticity through authorized channels due to discontinued status. Confirm RoHS compliance details via official documentation. Ensure storage conditions maintain integrity given the end-of-life classification. Cross-reference datasheet revisions to match specific manufacturing batches.

Selection Notes

Select this component when a 17.5 dB gain and 0.5 dB noise figure are required at 2 GHz. Compare against ATF-34143-TR2G for identical electrical specifications but different packaging configurations. Evaluate thermal management requirements based on the 725 mW power dissipation limit within the SOT-343 footprint.

Part Context

This part belongs to the ATF-34143 series of GaAs pHEMT transistors from Broadcom. It shares core electrical characteristics with other variants like the ATF-34143-BLKG and ATF-34143-TR2G, differing primarily in packaging and reel specifications. The series is designed for general-purpose low-noise amplification in RF applications.

Replacement Considerations

ATF-34143-TR2G offers identical electrical parameters including 17.5 dB gain and 0.5 dB noise figure. Verify pinout compatibility and thermal resistance differences between TR1 and TR2G packaging before substitution.
