Part Review and Datasheet Update
Thought for 2 mins 46 sec
Done - I added the missing Datasheet URL property and pointed it to the official Quectel PDF.
I followed the part-review workflow of using the datasheet as the source of truth, checking existing project properties first, then comparing terminals and footprint data against the datasheet-defined package information

- Mechanical outline and antenna dimensions
- A pad pattern showing 9 x 1.50 pads along one side
- Host-PCB implementation guidance
- Ground-plane dependence
- Optional tuning with a PI matching circuit
- No schematic symbol
- No pin definition table
- No explicit pad numbering map
- No explicit feed-pad vs ground-pad naming in the extracted text
Table
| Area | Project | Datasheet | Result |
|---|---|---|---|
| Terminal count | 2 terminal elements | Datasheet drawing suggests 9 physical solder pads | Potential mismatch |
| Pin numbering | Project uses only 5 and 6 | Datasheet extract does not provide numbered pad definitions | Cannot fully verify |
| Pin descriptions | Missing | Datasheet extract does not provide explicit pin descriptions | Not verifiable |
| Footprint pad count | Layout data shows a 9-pad physical pattern in the footprint structure | Datasheet drawing also suggests 9 pads | Looks consistent mechanically |
| Symbol completeness | Only 2 electrical terminals are defined | Datasheet does not define a symbol | Ambiguous, but likely intentional if only feed/return are meant to be exposed electrically |
- Good: the official datasheet is now attached, and the mechanical footprint appears broadly consistent with the datasheet's 9-pad style.
- Main issue: the project currently exposes only 2 terminals, while the package drawing appears to have 9 solder pads.
- Important nuance: this is not automatically wrong for an antenna part. It may be that only 2 pads are electrically meaningful and the remaining pads are mechanical / ground / support features. But the datasheet extract I could retrieve does not explicitly confirm that, so I cannot validate the current pin mapping with confidence.
Table
| Priority | Action |
|---|---|
| High | Add Manufacturer Name = Quectel |
| High | Add Package or Case Code based on the mechanical package naming you want to use |
| High | Manually inspect the datasheet drawing page to confirm whether pads 1-4 and 7-9 are ground/mechanical pads, and whether only pads 5-6 are intended as electrical terminals |
| Medium | Add pin descriptions once the pad functions are confirmed |
| Medium | Tighten the project description to match the datasheet wording: embedded LPWA/ISM / LTE SMD PCB chip monopole antenna |
If you want, I can do the next pass and populate the missing metadata fields, then propose how the two exposed terminals should be labeled based on the footprint and antenna application.
