Figures Antenna interface with MAGPIO controlled antenna impedance tuner and Antenna interface with MIPI RFFE controlled active antenna show examples of antenna interfaces including nRF9160 and an antenna tuner.
In Antenna interface with MAGPIO controlled antenna impedance tuner, the MAGPIO interface is used to control the antenna impedance tuner. As three MAGPIOs are available, a maximum of eight states of the antenna tuner can be supported.
Antenna interface with MIPI RFFE controlled active antenna shows the RF interface which includes nRF9160 and an antenna tuner controlled by MIPI RF Front-End Control Interface (RFFE). In MIPI RFFE, the number of different states is not limited by the number of available control lines. Therefore, it provides antenna tuners a more flexible control interface than MAGPIOs.
