Implementation of SMA Connector
Notes on implementing an SMA connector
This document provides important notes regarding the radio certification of the SMA connector (TWELITE-SMD-SMA-CONN).
The reference design is published at the following location.
monowireless/PCB_REF_DESIGN_KICAD: Reference Schematic/PCB design data for KiCAD
Requirements
Common
- Wire according to the pattern and through-holes as specified in the design data
- Do not modify areas marked as “No wiring, DO NOT WIRE” in the design data
- Use the specified printed circuit board
- Specify a thickness of 1mm to the PCB manufacturer
- Due to dielectric constant considerations, use glass epoxy (FR-4); other materials are not allowed
- Layer structure should be double-sided or 4-layer
- There are no specific requirements for solder resist color or silk screen
- Confirm that manufacturing and assembly are according to the design
- Ensure no design deviations exceed commonly cited tolerances
- Confirm that the wireless module is properly mounted
- Use the specified connector
