D. Design and testing verification for ensuring compliance
 Follow the reference design using the same components as when integrating the SDC-SSD40L.
 Use the same PCB material (FR4) with the same board stake thickness (0.062”).
 The RF trace between the SDC-SSD40L (Pin 56) and the antenna connector (J1) should be
controlled within 50 ohm +/-10%; keep the trace as short as possible (less than 100 mils is
recommended) to reduce the trace loss.
 Place 10 mils through via hole with 40 miles distance apart.
 Use TDR to confirm the RF trace is within 50 ohm +/-10%.
 Use the spectrum analyzer to confirm the radiate signal is within the certification limit.
Documentation Requirements
In order to ensure regulatory compliance, when integrating the SDC-SSD40L (Model # SDC-SSD40L)
into a host device, it is necessary to meet the documentation requirements set forth by the applicable
regulatory agencies. The following sections (FCC, Industry Canada, and European Union) outline the
information that may be included in the user’s guide and external labels for the host devices into which
the SDC-SSD40L is integrated.
FCC
Note: You must place “Contains FCC ID: TWG-SDCSSD40L” on the host product in such a location that
it can be seen by an operator at the time of purchase.
