Automotive Systems, Inc.
ii. During manufacturing process of the integrated device, the module is soldered onto the pcb of the
integrated device.
iii. The integrated device must provide RF connectors to external antennas or RF traces to connect the
FE4NA0210 modules to antennas inside the integrated device. The typical reference design for the
RF trace layout, including pcb stack-up and trace length is described in Section 6 of this document.
iv. Automotive OEM is responsible for ensuring that the end-user has no manual instructions to
remove or install module.
v. The module is limited to installation in mobile applications, according to Part 2.1091(b).
vi. No other operation configurations are allowed.
vii. Changes or modifications to this system by other than a facility authorized by Continental could
void authorization to use this equipment.
viii. The module does not have a pre-defined antenna. Under No conditions may an antenna gain be
used that would exceed the ERP and EIRP power limit as specified in Part 22, Part 24 and Part 27.

6 Layout and Routing Recommendations
6.1 Module Specific
The pad spacing of 0.7mm should allow the placement of a 450um finished VIA between pads, while
maintaining a 125um via-to-trace or via-to-pad spacing, to facilitate the breakout of inner row
signals. The 0.7mm spacing is also large enough to route two 160um (6mil) traces between pads.
Figure 1: Vias placed between Pads
6.2 RF Traces for antennas
The NAD has eight antenna pins.
• LTE_ANT_1
• LTE_ANT_2
• LTE_ANT_3
• LTE_ANT_4
• GNSS_ANT_1
• GNSS_ANT_2
• CV2X_ANT_1
• CV2X_ANT_2
Multi-transmission is not possible. The figure below shows the general breakout of the module:
Figure 2: NAD Pin Breakout
The FE4NA0210 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.
The RF traces from the NAD antenna pins on the main board can be stripline or microstrip.
For routing microstrip lines UNDERNEATH the NAD on layer 1, these ground cutouts internal to the
NAD need to be accounted for in the stripline calculation. The internal GND height and dielectric
constant of the NAD board are shown below:
H = 19.3 mils (491 micron)
Dielectric Constant = 4.1
For example, consider the following stackup for a main PCB:
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
The calculation for the microstrip line width outside the NAD is 37.7mils (967micron) shown below:
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.
Main board stack up may vary so these line widths may need to be recalculated. IT IS HIGHLY
RECOMMENDED TO USE A SIMILAR STACKUP AS SHOWN IN FIGURE 3.
Antenna Routing Recommendations:
1. Microstrip routes on layer1 and very short route under the NAD.
Figure 6: Antenna Line Microstrip Routes on Layer1
2. Then routes to inner layer and continues route as stripline.
Figure 7: Antenna Line Stripline Routes On Inner Layer
These line widths may vary depending on the stack up selected for the main board.
6.3 RF Antenna Layout Parameters
Type of Guidance
Requirement
Trace impedance
50-Ohms ± 10% single-ended
Total route length
<100-mm
Ground between signals
> 1 x line width of ground trace between, stitched VIA to ground
Ground between signals
> 3 x line width of ground trace between, stitched VIA to ground
Spacing to other signals
< 3:1
• The RF signals should be routed STRAIGHT OUT OF THE NAD TO THE NEAREST EDGE along
similar route pat but separated by ground trace.
• Trace impedances should match the table, either as microstrip or stripline.
• Total length for both signals should be kept to a minimum always optimizing the PRIMARY_ANT
(LTE_ANT_1) path.
• Spacing to ground or other signals on outside of bundled signals should match the table.
