Reference circuitry
To ensure good RF performance when designing PCBs, it is highly recommended to use the PCB layouts
and component values provided by Nordic Semiconductor.
Documentation for the different package reference circuits, including Altium Designer files, PCB layout
files, and PCB production files can be downloaded from www.nordicsemi.com.
Note: In this context reference circuitry illustrates the vehicle (i.e. nRF9160 Development Kit)
applicable for the nRF9160 module granted the FCC certifications listed in Supported FCC rules on
page 5. The given reference circuity is a valid generic example of an nRF9160 based final device but
does not limit the use of nRF9160 in any way.
6.1 Schematics
The following figure illustrates the reference schematics of nRF9160 Development Kit.

6.2 PCB layout
The PCB layout shown in Figure 9: nRF9160 reference layout, metal layer 1 (top) on page 18 and
Figure 10: nRF9160 reference layout, metal layer 2 on page 18 are part of the nRF9160 Development
Kit reference layout. The figures show the PCB design details of the area where the cellular antenna is
located.
