PRODUCT SPECIFICATION
nRF9E5 Single Chip Transceiver with Embedded Microcontroller and ADC
21.3 Single Ended Connection to 50 Antenna
Figure 39 868-915MHz operating nRF9E5 application schematic, single ended
connection to 50 antenna by using a differential to single ended matching network.
It is recommended to add pull up or pull down resistors on signals that can enter a
floating state. For the nRF9E5 it is recommended to have pull down on the MISO signal.
