Part Review and Datasheet Update

flux

  • Set Implementation Details to "Discontinued product. 50Ω RF ports. LNA_BIAS may be left floating for high-bias mode or tied to GND through 51kΩ for low-bias..."
  • Set Operating Temperature to "-40 to +85"
  • Set Compliance to "RoHS, Lead-Free, Halogen-Free; ECCN EAR99; ITAR No"

flux

  • Set GND's Pin Type to "Ground"
  • Set GND's Pin Description to "Central ground paddle / extra footprint pad; not listed in 32-pin datasheet table"
  • Set GND's Section to "Ground"
  • Set GND's Pin Group to "Ground"
  • Set GND's Pin Orientation to "Bottom"

flux

Updated the RFFM6901 part metadata with the official Qorvo datasheet URL, manufacturer/package/spec properties, project description, and synchronized terminal pin descriptions/types to the datasheet. The main issue found is a 32-pin datasheet table versus 33 project terminals/footprint pads; the extra GND pin 33 was documented as likely central ground paddle/extra footprint pad for review. Full details are in the RFFM6901 Datasheet Synchronization Report.
