Clear instructions describing the other partys responsibility to obtain station licensing. 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 FE4RW0110NADs 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 Trace impedance Total route length Ground between signals Ground between signals Spacing to other signals Requirement 50-Ohms 10% single-ended

<100-mm

> 1 x line width of ground trace between, stitched VIA to ground

> 3 x line width of ground trace between, stitched VIA to ground

< 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 Spacing to ground or other signals on outside of bundled signals should match the table.
