NAD Module RF Characteristics

All RF parameters are referenced at the antenna terminals of the NAD. The RF performance of the host device (i.e. TCU) can differ depending on the additional line losses ­ as well as the impedance match ­ presented to each of the NAD’s antenna terminals.

• WCDMA bands: + 23.0 dBm to +1.0/-2.0 dB
• LTE bands: +23 dBm +1.0/-2.0 dB
• EN-DC with NR Bands (unless noted as PC2) Combined Power: +23 dBm +1.0/-2.0 dB (PC3)
• EN-DC with n77 Band Combined Power: +26 dBm +1.0/-2.0 dB (PC2)
• 5G SA bands (unless noted as PC2): +23 dBm +1.0/-2.0 dB (PC3)
• 5G SA n41 and n77 HPUE: +26 dBm +1.0/-2.0 (PC2)

NAD Module RF Receiver Sensitivity

Storage and Handling

Moisture Sensitivity Level (MSL)

All NAD modules are moisture sensitive and should be kept in their sealed moisture resistant bags until ready for assembly onto the DCM via the soldering process. Any parts that are not used immediately should be properly resealed in the same moisture resistant bag using appropriate equipment or placed into a dry box until they are needed again. The moisture sensitivity level (MSL) shown below is the amount of time the NAD modules may be exposed before this action must be taken. If the allowed MSL time elapses, the NAD modules must be baked per standard protocol to remove moisture.
Moisture Sensitivity Level: MSL Level 3 (1 Week)

Layout and Routing Recommendations

ANTENNAS

The NAD has eight antenna pins.

• LTE/5G NR: LTE_ANT_1 – LTE_ANT_4
• GNSS: GNSS_ANT_1, GNSS_ANT_2

NAD Antenna Breakout
To route to the NAD terminals on the parent PCB, microstrip on the bottom (opposite NAD) layer is the best choice, with vias to the NAD side located as close as possible to the NAD antenna terminals. It is not recommended to route antenna traces to the NAD terminals on the top (NAD) side of the parent PCB, where they would be directly underneath the NAD; significant RF performance degradation would occur. It is likely that the parent device’s PCB will use only thru-hole vias, and so the antenna pads on the parent PCB may need to be offset slightly from their vias for manufacturability reasons. The NAD bottom layers have been designed to accommodate this need, and ground cutout in these layers has been extended to avoid shorting to those vias on the parent PCB’s top layer, where it mates with the NAD. Figure 9-1 details the ground cutout provided on the bottom six layers of the NAD, and the PCB of the parent device should utilize this cutout area for placement of any thru vias which serve the antenna pads:

Figure 9-1: Antenna Pad Ground Cutouts (NAD bottom layer)

Figure 9-2 provides a more detailed view of the cutout around each antenna pad on the NAD PCB.

Figure 9-2 Antenna Pad Ground Cutout x8 (detail view)

Table 9-1: RF Antenna Layout Parameters

layer
Spacing to other signals| > 3 times RF line width, to any non-RF traces
VSWR for Cellular Antenna ports| < 3:1

• Trace impedances apply to either microstrip or strapline.
• Length for all antenna traces should be kept to a minimum, with priority on cellular antenna 1.

Integrated Device RF Insertion Loss
The integrated device TX and RX performance must comply with 3GPP and MNO RF requirements at the RF connectors. In addition, in some use cases, such as on- board antenna, TRP and TIS performance requirements must be met. It is a Product Team’s responsibility to insure the integrated device complies with these requirements.
The Insertion Loss between NAD’s RF and the host module antenna terminal (RF connector of the evaluation board or the Telematics/host module) must be kept at minimum and not to exceed these values:

• RF Loss < 0.6dB from 700 – 1000MHz
• RF Loss < 1.2dB from 1.7 – 2.7GHz
• RF Loss < 2.0dB from 2.7 – 6.0GHz

SDC / eMMC Routing

Table 9-2: SDC / eMMC Layout Parameters

• Trace impedances should follow table, either as microstrip or strapline.
• Trace lengths should follow table.
• Number of vias per trace should follow table.
• No stubs allowed on traces.
• No test points allowed on traces.
• Trace lengths should follow table.
• Spacing to ground or other signals on outside of bundled signals should follow table.
