FE4CNX210 Module The FE4CNX210 NAD is a proprietary embedded module designed by Continental Automotive Systems, Inc. The modules will be integrated into Data Connectivity Modules (DCM-TCUs) or USB hosts (HUs) designed and produced by Continental or by a 3rd party for use by automotive OEMs. DCM-TCUs will be installed into vehicles during the OEM’s factory assembly process and will not be accessible without... - Page 4 « Le pré sent é metteur radio (2807E-FE4CNX210) a é té approuvé par Industrie Canada pour fonctionner avec les types d'antenne é numé ré s ci-dessous et ayant un gain admissible maximal.

- Page 7 Figure 2: NAD Pin Breakout The FE4CNX210 NAD should be oriented on the main board to minimize the length of the primary LTE TX/RX antenna (LTE_ANT_1). This 50ohm line should be as short as possible to the external RF connector or internal antenna feed point.
- Page 8 Figure 3: Recommended PCB Stack-up Assume the main PCB above with a 6 layer stack up with ground cut away on layer 2 so the microstrip lines reference ground on layer 3. The dielectric thickness from L1 to L3 is 21.2 mils. Using an online impedance calculator, the line width under the NAD for a 50 ohm line is 15.9mils (405micron) shown below: Figure 4: Stripline Impedance Calculations...
- Page 9 Figure 5: Microstrip Impedance Calculations Due to the nature of the weave chosen for each PCB, the dielectric constant of the NAD board is 4.1 while the main board is 4.3. A dielectric constant of 4.2 was chosen in the stripline calculation, while 4.3 was used for the microstrip calculation.
