RF measurements
The nRF9160 DK is equipped with a small size coaxial connectors J1 and J7 for measuring the RF signal for
LTE and 2.4 GHz.
The connectors are of SWF type (Murata part no. MM8130-2600) with an internal switch. By default, when
no cable is attached, the RF signal is routed to the onboard antenna. The insertion loss in the adapter
cable is approximately 0.5–1 dB.
An adapter is available (Murata part no. MXHS83QE3000) with a standard SMA connection on the other
end for connecting instruments (the adapter is not included in the kit). When connecting the adapter, the
internal switch in the SWF connector will disconnect the onboard antenna and connect the RF signal from
the nRF9160 to the adapter.
