ix. The integrator is responsible for fulfilling FCC and IC requirements for the integrated device.
If Continental chooses to re-use modular approval, then the TCU shall be clearly labeled with an external
label containing the integrated modem’s FCC ID. For example, the label can include text “Contains device
with FCC ID: LHJ-BL28NA001 and IC: 2807E-BL28NA001”.
4 Antenna requirements for use with BL28NA-001 module:





The module must be installed to provide a separation distance of at least 20cm from all persons
and must not be co-located or operating in conjunction with any other antenna or transmitter.
The BL28NA-001 module is for use with external antennas ONLY.

The maximum gain of the antenna path (cable loss + antenna gain) shall not exceed the above
mentioned values.
This radio transmitter (FCC ID: LHJ-BL28NA001; IC: 2807E-BL28NA001) has been approved
by FCC and Industry Canada to operate with the antenna types listed below with the maximum
permissible gain indicated. Antenna types not included in this list, having a gain greater than the

5 Instructions to OEMs:
Continental must instruct the automotive OEM and provide them to include the following
information into the car user’s manual (i.e. for the DCM):

24E, and 27.
6. Clear instructions describing the other party’s responsibility to obtain station licensing.
6 Layout and Routing Recommendations
6.1
Module Specific
The pad spacing of 1mm should allow the placement of a 600um 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 200um traces between pads.
Figure 6-1 Vias placed between Pads
BL28NA-001 OEM Manual and User Guide
6.2
Power Pins
Application note - External decoupling capacitors requirements for the critical NAD internal power supplies
For each of the four NAD supply pins, place two external decoupling capacitors, a 1 uF and a 10uF, as
close as possible to each of these four power pins (G14, H14, J14, and K15). Figure 6-1shows the four
power pins on the NAD
NEEDS TO BE UPDATED
Figure 6-1. Through the part view of pads on the module.
Keep routing of these capacitors, both to the power pins and to the grounds, direct and as short as possible.
Use minimum 3 VIA pairs (minimum 3 VIAs for power and minimum3 VIAs for ground), placed close to
the pins and routed with a wide trace or area fill. Figure 6-2 depicts the recommended placement and
routing for these decoupling capacitors on the TCU board.

RF Traces for antennas
The NAD has five antenna pins.

PRIMARY_ANT
SECONDARY_ANT
WIFI_ANT_0
WIFI_ANT_1
GNSS_ANT
The figure below shows the general breakout of the LTE-A NAD:
The LTE_A NAD should be oriented on the main board to optimize the length of the PRIMARY_LTE
antenna pin. This line should be as short as possible.
The RF traces from the NAD antenna pins on the main board can be stripline or microstrip. If stripline is
chosen, the VIA should be placed as close as possible to the NAD antenna pads to minimize any
impedance discontinuity. If microstrip is chosen, the PCB insertion loss will be less, but the short route
under the NAD must be treated as stripline.
The NAD has ground cleared out under the RF antenna routes as shown below:
Figure 6-3
These ground cutouts need to be accounted for in the stripline calculation underneath the NAD. The height
and dielectric constant of the NAD board are shown below:
H = 21.6 mils (553 micron)
Dielectric Constant = 4.1
BL28NA-001 OEM Manual and User Guide
For example, consider the following stackup for a main PCB:
Figure 6-4
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:
Figure 6-5
BL28NA-001 OEM Manual and User Guide
The calculation for the microstrip line width outside the NAD is 37.7mils (967micron) shown below:
Figure 6-6
The dielectric constant of the NAD board is 3.5 while the main board is 3.6 due to the nature of the weaves
chosen for each PCB. A dielectric constant of 3.5 was chosen in the stripline calculation while 3.6 was
used for the micro-strip calculation The antenna lines need to be tapered from the 433micron width to the
967micron width gradually but quickly as shown below:
Figure 6-7
BL28NA-001 OEM Manual and User Guide
These line widths may vary depending on the stackup selected for the main board.
