Part Datasheet Review and Validation

flux

I’ll inspect the part metadata and CAD data, find/update any missing official datasheet link, then compare symbol/footprint/pins against the datasheet and summarize mismatches.

Review complete.
  • Datasheet URL is already set to the official ST URL: https://www.st.com/resource/en/datasheet/balfhb-wl-06d3.pdf
  • MPN/manufacturer match: BALFHB-WL-06D3, STMicroelectronics
  • Pin count matches: 8 pads/bumps
  • Symbol terminal mapping matches the datasheet pinout:
    • A1 RFO_in, A2 RFI_N_out, A3 RFI_P_out
    • B1 GND2, B2 GND3
    • C1 RFO_out, C2 GND1, C3 RFI_in
  • Key specs: 862–928 MHz, 50 Ω antenna-side Tx/Rx, STM32WL-matched differential Rx / Tx ports, integrated harmonic filter, CSPG 8-bump package, operating temp -40 to +105 °C, HBM ESD 2 kV.
Flagged mismatches:
  • Library/package property says QFN, but datasheet package is CSPG 8 bumps.
  • Part classification appears generic/incorrect: Integrated Circuits / Logic / AND; this should be an RF balun / RF filter front-end component.
  • Project checks report one unrelated issue: missing project documentation.
