FCC Modular Certification Requirements

Because these modules and their associated set of approved antennas has been certified by the FCC and Industry Canada (IC) as Modular Radios, the end user is authorized to integrate this module into an end-product and is solely responsible for the Unintentional Emissions levels produced by the end-product.

To uphold the Modular Radio certifications, the integrator of the module must abide by the PCB layout recommendations outlined in the following paragraphs. Any divergence from these recommendations will invalidate the modular radio certifications and require the integrator to re-certify the module and/or end-product.

The module must be used with one of the approved antennas:

Table 4: Sona Approved Antennas

When using the module and the reference design that supports the off module MH4 connector(s), you may use a substitute antenna if it is of the same type and that the gain is less than or equal to the smallest gain for that type for each of the frequencies listed.

Ezurio provides a FCC Modular Certified reference design. It is a controlled impedance PCB that uses microstrip trace design to route RF signals from the module to the coaxial connectors.

Please use the latest CAD files from the Ezurio web site when incorporating the Sona™ module into a new design. CAD files are provided in native Altium as well as Gerber and PDF formats.

Sona NX611 SIP Certified Module Host Board Requirements

Table 5: Sona NX611 SIP Modules

The reference design for the Ezurio Sona NX611 SIP Module has been integrated into the Sona NX611 Development Board. It is 6-layer PCB with a total thickness of 0.79mm. The reference design includes designs for the singe port version as well as the dual port version.

To comply with FCC regulations, the RF area of host design must match the RF area of the reference design exactly. To match exactly, the distance from the top layer to the RF reference ground plane on host PCB and the Dk of the host board must match the Reference design. When the reference ground plane and Dk of the host board match, the 50 ohm RF trace widths will be the same and the host board copper can match the reference board copper.

In addition to matching the reference design layout, there are several RF critical BOM components in the reference design that cannot be substituted shown in Table 6.

Sona™ NX611 M.2 2230 Module Mounting Guidelines

The Sona NX611 M.2 2230 module connects to the host via a standard PCI EXPRESS M2 connector. The Kyocera (www.Kyocera-connector.com) 6411 series provides 1.8 mm, 2.3 mm and 3.2 mm connector heights and the JAE (https://www.jae.com/en/) SM3 series provides 1.2 mm, 2.15 mm, 3.1 mm and 4.1 mm connector heights. 

Because the Sona NX611 M.2 module is a single-side component module, we recommend the following part numbers which have 2.3 mm and 3.1 mm connector height:
