Implementation of SMA Connector

This document provides important notes regarding the radio certification of the SMA connector (TWELITE-SMD-SMA-CONN).

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
