The nRF9161 DK has antenna interfaces for Long-Term Evolution (LTE) and Global Navigation Satellite System (GNSS). DECT NR+ uses the same on-board antenna as LTE.
The LTE signal is propagated through a coaxial connector with a switch that disconnects the antenna from the radio if an adapter cable is connected. This makes it possible to perform conducted measurements or to attach external antennas to the radio.
The GNSS signal is RX only. A Low-Noise Amplifier (LNA) with integrated filters amplifies and filters the signal before it is fed to the GNSS RF port on the nRF9161 DK. An external active GNSS antenna can be connected to J2. When using an external antenna, the LNA should be disabled.
The DK has the following antenna interface connectors:
