NAD Module RF Characteristics
All RF parameters are referenced at the antenna terminals of the NAD. The RF performance of the parent 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.

NAD Module RF Transmitter Output Power
The Transmitter Power at the NAD antenna terminal (not the RF connector of the evaluation board or the Telematics/parent module) at Room Temperature:

• GSM low bands (800/900): +32.5 +1.0/-2.0 dBm
• GSM hi bands (1800/1900): +29.5 +1.0/-2.0 dBm
• EDGE low bands (800/900): +26.5 +1.0/-2.0 dBm
• EDGE hi bands (1800/1900): +25.5 +1.0/-2.0 dBm
• WCDMA bands: +23.0 +1.0/-2.0 dBm
• LTE bands (PC3): +23.0 +1.0/-2.0 dBm*
• LTE bands (PC2): +26.0 +1.0/-2.0 dBm**
• 5G NR bands (PC3): +23.0 +1.0/-2.0 dBm*
• 5G NR bands (PC2): +26.0 +1.0/-2.0 dBm**

For most bands. Some exceptions exist, based on the 3GPP standard.
For antenna ports that are HPUE capable on specific LTE and 5G NR bands.

Allowance for a reduction in maximum transmitter power is specified in the 3GPP standard for GSM multi-slot operation (MSPP=0). The SA515 ReDtc NAD adjusts the GSM maximum TX power in these cases per Table 5-1.
Table 5-1: GSM Multi-slot power reduction

Band

| GSM/EDGE Multi-slot maximum output power reduction
---|---
2 slots| 3 slots| 4 slots
GSM| 3.0 dB| 4.5 dB| 6.0 dB
EDGE| 2.0 dB| 3.0 dB| 4.0 dB

NAD Module RF Receiver Sensitivity
The Receiver Sensitivity at the NAD antenna terminal (not the RF port of the evaluation board or the Telematics/parent module) at Room Temperature:

• GSM lo bands (800/900): 3GPP TS 05.05 Section 6.2
• GSM hi bands (1800/1900): 3GPP TS 05.05 Section 6.2
• WCDMA bands: 3GPP TS 34.121-1 Section 6.2
• LTE bands: 3GPP TS GPP 36.521 Section 7.3
• 5G NR bands: 3GPP TS GPP 38.521 Section 7.3
• C-V2X bands: 3GPP TS GPP 36.521 Section 7.3G
• GNSS bands: -163 dBm (in Out-Of-Service mode)1

The NAD is designed to be paired with an external active GNSS antenna system having 17 to 20 dB of net gain and noise figure <=2.5 dB. The NAD by itself is not expected to achieve the stated RF sensitivity on the GNSS bands.

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)

Electrostatic Discharge
The NAD is generally well-protected from ESD by conductive full shielding when mounted on the parent device where adequate protections have been taken at the NAD electrical interfaces.
As a stand-alone device, such protection is absent, and care must be taken to protect the NAD from ESD during handling before placement onto the parent device.

Material Statement
The End-of-Life Vehicle Directive (EVL) must be applied to the FE5NAR131 module. This means that the component is included in the overall vehicle (since it is permanently installed) and if the explanation of the materials used and, if applicable, disposal descriptions from the vehicle manufacturer.
