Clear instructions describing the other partys responsibility to obtain station licensing. 24E, and 27. 6 Layout and Routing Recommendations Module Specific 6.1 The pad spacing of 1mm should allow the placement of a 600m finished VIA between pads, while maintaining a 200um Via- to-trace or Via-pad spacing, to facilitate the breakout of inner row signals. The 1mm spacing is also large enough to route two 200m (8 mil) traces between pads. Figure 6-1 Vias placed between Pads 6.2 The NAD has three antenna pins. RF Traces for antennas PRIMARY_ANT SECOND_ANT BL28NA-001 OEM Manual and User Guide GNSS_ANT The figure below shows the general breakout of the module:

Figure 6-2: NAD Pin Breakout The LTE CAT4 NAD should be oriented on the main board to minimize the length of the PRIMARY_LTE antenna pin (LTE Ant1). 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 the stripline approach, vias should be placed to the NAD EDGE SIDE of the pins as close as possible to the NAD antenna pads to minimize any impedance discontinuity (see figure 38). For the microstrip approach, the PCB insertion loss will be less but the short route under the NAD MUST BE TREATED AS STRIPLINE SO IT WILL BE NARROWER UNDER THE NAD THAN THE MICROSTRIP LINE. BL28NA-001 OEM Manual and User Guide The NAD has ground cleared out under the RF antenna routes as shown below:

Figure 6-2: Antenna Pad Ground Cutout (Top View) 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 6-3 BL28NA-001 OEM Manual and User Guide Assume the main PCB above with a 6 layer stackup 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 16.9mils

(433micron) shown below:

BL Figure 6-4 The calculation for the microstrip line width outside the NAD is 37.7mils (967micron) shown below:

Figure 6-5 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 39 WITH MICROSTRIP BL28NA-001 OEM Manual and User Guide ROUTING AND GND CUTS ON LAYER 2 WITH GND REFERENCE ON LAYER 3. THERE SHOULD BE NO ROUTING ON L2 AND SOLID GND ON L3 UNDERNEATH THESE ANTENNA LINE MICROSTRIP TRACES. The antenna traces need to routed STRAIGHT OUT OF THE NAD TO THE NEAREST NAD EDGE. The lines need to be tapered from 433micron to the 967micron width gradually but quickly. Figure 6-6 These line widths may vary depending on the stackup selected for the main board. 6.3 RF Antenna Layout Parameters Type of Guidance Trace impedance Total route length Ground between signals Spacing to other signals Requirement 50-Ohms 10% single-ended

<100-mm

< 3:1 Signals should be routed along similar route path, but separated by ground trace. Trace impedances should match the table, either as microstrip or stripline. Total length for both signals should match the table. Spacing to ground or other signals on outside of bundled signals should match the table.
