5. Regulatory Compliance Consideration
Depending on the region where the end-product will be operating in, both CE and FCC are necessary for system
level products.
If the end-product has a custom antenna, it is the integrator’s responsibility to make sure that the antenna being
used is in compliance with all the laws for the country, frequency, and power levels in which the device is used.
Additionally, some countries regulate reception in certain frequency bands. It is the end integrator’s responsibility
to maintain compliance with all local laws and regulations. To facilitate compliance testing, the certification test
instruction [4] is available for download at https://www.northernmechatronics.com/nm180100
.
In order to leverage the NM180100 modular certification, the peak and average gain of the antenna must be equal
to or less than the reference antenna as shown in the table below.

6. Production Testing Consideration
End product production testing is highly recommended to ensure regulatory compliance. Since each module is
completely characterized during manufacturing, end-product RF testing of the NM180100 is straight forward. In
order to measure the RF performance, a switched RF coaxial connector can be placed in-line with the RF path such
as a Murata MM8430-2610RA1 used in the NM180100EVB. Figure 8 and Figure 9 show example implementations
on where the connector would be placed for a single or a dual antenna implementation respectively.
Figure 9 Dual antenna switched RF coaxial connectors (J1 and J2) placement.
Figure 10 Single antenna switched RF coaxial connector (J3) placement.
