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

GNSS:

GNSS_ANT_1, GNSS_ANT_2 LTE_ANT_1 LTE_ANT_4 9.1.1 NAD Antenna Breakout The 5G NAD should be oriented on the main board to minimize the length of the primary Cellular TX/RX antenna (ANT1). This 50ohm line should be as short as possible to the external RF connector or internal antenna feed point. The RF traces on the main board connecting from the NAD antenna pins can be either stripline or microstrip, but the microstrip routing must be on the layer opposite from the NAD, since the bottom layer of the NAD will be mostly ground and it would become a near RF short to any trace that ru ns on the main boards top layer, while still underneath the NAD. For a given line length, the stripline approach will tend to be more lossy, so it is generally not recommended. Thus, microstrip antenna lines are favored in most cases. 9.1.1.1 NAD Antenna Pad Ground Cutout It is likely that the host devices PCB will use only thru-hole vias, and so the antenna pads on the host PCB may need to be offset slightly from their vias for manufacturability reasons. The NAD bottom layers have been designed to accomodate this need, and ground cutout in these layers has been extended to avoid shorting to those vias on the host PCBs top layer, where it mates with the NAD. Figure 9-3 details the ground cutout provided on the bottom six layers of the NAD. The PCB of the host device should utilize this cutout area for placement of any thru vias which serve the antenna pads:

Internal FE5NA0020 Specification Figure 9-1: Antenna Pad Ground Cutouts (NAD bottom layer) Figure 9-4 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) 9.1.1.2 Host PCB Antenna Pad Design Recommendation The main board on which the 5G NAD will be mounted should have ground cut out under the RF antenna pins of the NAD as shown in Figure 9-3 and Figure 9-4:

Figure 9-3: Antenna Pad Ground Cutout Recommended (Main Board, top layer/NAD side) Internal FE5NA0020 Specification Figure 9-4 Antenna Pad Ground Cutout x8 (detail view) The dimensions of the RF trace on the Main Board will be dependent on the layer stack-up of the board, their thicknesses and how many layers are used. As an example, the main PCB shown in Figure 9-5 is a 6 layer stack up with Ground cut out on layer 5 so the microstrip lines on the bottom (layer 6) reference Ground on layer 4. For this example, the dielectric thickness from L6 to L4 is 21.2 mils. Figure 9-5: Recommended PCB Stack-up Using any common microstrip impedance calculation tool, the result for a 50-ohm microstrip line (in typical dialectric constant of 4.3) with the height in the above example yields a width [w] of 37.7mils

(967micron). The line width will of course vary, particularly depending on the stack up and use of layers on the main board. In the end, the characteristics of the RF traces connecting to the NAD on the main board should remain within the guidelines of Table 9-1.

In addition, in some use cases, such as on-board antenna, TRP and TIS performance requirements must be met. It is a Product Teams responsibility to insure the integrated device complies with these requirements. The Insertion Loss between NADs 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:

Above mentioned document contains detailed system and equipment description are considered as proprietary information in operation of the equipment. The public disclosure of above documents might be harmful to our company and would give competitor an unfair advantage in the market. In additional to above mentioned documents, pursuant to Public Notice DA 04-1705 of the Commission s policy, in order to comply with the marketing regulations in 47 CFT 2.803 and the importation rules in 47 CFR 2.1204, while ensuring that business sensitive information remains confidential until the actual marketing of newly authorized devices. We are requesting the commission to grant short-term confidentiality request on the following attachments until 180 days after the Grant Date of Equipment Authorizations. It is our understanding that all measurement test reports, FCC ID label format and correspondent during certification review process cannot be granted as confidential documents and those information will be available for public review once the grant of equipment authorization is issued.

Continental Automotive Systems, Inc. 21440 W Lake Cook Rd., Deer Park, IL 60010, USA Modular Approval Request FCC (KDB 996369 D01 & Part 15.212) FCC ID: LHJ-FE5NA0020 Items to be covered by Single modular transmitters. Answer from applicant 1. The modular transmitter must have its own RF shielding. 2. The modular transmitter must have buffered modulation/data inputs (if such inputs are provided) to ensure that the module will comply with Part 15 requirements under conditions of excessive data rates or over-modulation. 3. The modular transmitter must have its own power supply regulation. The modular transmitter must comply with the antenna requirements of Section 15.203 and 15.204(b)(c). The antenna must either be permanently attached or employ a unique antenna coupler (at all connections between the module and the antenna, including the cable). 4. 5. The modular transmitter must be tested in a stand-alone configuration, i.e., the module must not be inside another device during testing. This is intended to demonstrate that the module is capable of complying with Part 15 emission limits regardless of the device into which it is eventually installed. The required rule has been fulfilled. 6. The modular transmitter must be equipped with either a permanently affixed label or must be capable of electronically displaying its FCC identification number in accordance with 15.212 (a)(1)(vi)(A) / (B). The radio portion of this module is shielded. The module has buffer modulation/data inputs. The module has its own power supply regulation. The requirements of antenna connector and spurious emission have been fulfilled. The Module will be labeled with its own FCC ID, and the instruction on the labeling rule of the end product has been stated in the User Manual of this module. The required rule has been fulfilled and all the instructions for maintaining compliance have been clearly stated in the User Manual. 7. The modular transmitter must comply with any specific rule or operating requirements applicable to the transmitter and the manufacturer must provide adequate instructions along with the module to explain any such requirements. A copy of these instructions must be included in the application for equipment authorization. For example, there are very strict operational and timing requirements that must be met before a transmitter is authorized for operation under Section 15.231. For instance, data transmission is prohibited, except for operation under Section 15.231(e), in which case there are separate field strength level and timing requirements. Compliance with these requirements must be assured. 8. The modular transmitter must comply with any applicable RF exposure requirements. For example, FCC Rules in Sections 1.1310, 2.1091, 2.1093, and specific Sections of Part 15, including 15.319(i), 15.407(f), 15.253(f) and 15.255(g), require that Unlicensed PCS, UNII and millimeter wave devices perform routine environmental evaluation for RF Exposure to demonstrate The required rule has been fulfilled and all the instructions for maintaining Continental Automotive Systems, Inc. 21440 W Lake Cook Rd., Deer Park, IL 60010, USA compliance. In addition, spread spectrum transmitters operating under Section 15.247 are required to address RF Exposure compliance. Modular transmitters approved under other Sections of Part 15, when necessary, may also need to address certain RF Exposure concerns, typically by providing specific installation and operating instructions for users, installers and other interested parties to ensure compliance. compliance have been clearly stated in the User Manual. If you should have any question(s) regarding this declaration, please dont hesitate to contact us. Thank you!
