• LNA for WLAN, WLL/RLL, LEO, and MMDS Applications
• General Purpose Discrete PHEMT for Other Ultra Low Noise Applications

Procurement Notes

Verify the specific suffix BLKG against official Broadcom documentation to confirm lead-free status and tape-and-reel packaging details. Confirm product lifecycle status as discontinued or obsolete through authorized channels before procurement planning.

Selection Notes

Select this component for ultra-low noise applications requiring high dynamic range in the 450 MHz to 10 GHz frequency range. Ensure the SOT-343 package fits the PCB layout constraints and that the 5.5 V rated voltage aligns with the system bias requirements.

Part Context

This part belongs to the ATF-33143 series of low noise pHEMTs from Broadcom. It shares similar electrical characteristics with variants like ATF-33143-TR2G but differs in packaging and ordering suffixes. The series is designed for cellular and PCS base station applications.

Replacement Considerations

Check for ATF-33143-TR2G or ATF-33143-BLK as potential substitutes. Verify pinout compatibility and electrical parameter equivalence with the original datasheet before substitution.
