Symbol / pin cross-check
The datasheet indicates a 12-lead package plus exposed paddle, and exposed pads should be treated as real pins in part verification workflows . Your project has 13 terminals total, so the pin count is consistent.

Mismatches and gaps flagged 1) Pin count and names
  • No pin-count mismatch found.
  • Naming is mostly correct.
  • Minor naming cleanup only:
    • VIADJ vs datasheet style VIadj
    • EP could be labeled Paddle or EP/GND for clarity
2) Pin properties
All terminals currently have Pin Type = Unspecified. For part-project verification, Flux guidance expects exact pin numbers and mapped pin types from the datasheet, not generic placeholders . Recommended assignments:

RF-INInput
RF-OUT VDDOutput or Unspecified if you want to preserve its mixed RF/bias nature
VIADJInput
GND_1, GND_2, GND_3, GND_4, EPGround
NC_1, NC_2, NC_3, NC_4, NC_5Not Connected
3) Pin descriptions
  • I do not see pin description properties populated on the terminals.
  • These should be added as short functions, for example:
4) Footprint
  • The footprint pad set appears structurally consistent with the symbol:
    • pads exist for all 13 terminals, including EP
  • I could confirm pad-name/count consistency, but I could not fully verify pad geometry/dimensions from the project data returned here.
  • The datasheet points to Suggested PCB Layout PL-813 / 98-PL-813, so the remaining open check is whether the current footprint dimensions match that land pattern exactly.
5) Package metadata
  • Package or Case Code = QFN is a bit too generic.
  • Better metadata would be:
    • 3 x 3 mm 12-Lead QFN-Style
    • or DQ1225
Bottom line What matches
  • MPN
  • Manufacturer
  • Description intent
  • Pin count
  • Pin numbering
  • Symbol terminal names, with only minor naming polish needed
  • Footprint pad naming/count appears aligned with the symbol
What needs attention
  • Package or Case Code should be more specific
  • Datasheet URL exists but points to the product page, not the canonical PDF
  • All terminal Pin Type properties are still unspecified
  • Pin descriptions are missing
  • Footprint geometry still needs a dimensional check against PL-813 / DQ1225
If you want, I can do the next step and update the project properties plus terminal pin types/descriptions for you.
