4. RF Front End Interface
The SX1302 can accommodate any of the following RF front-end devices: SX1250, SX1255 and SX1257, all of which are
Semtech products. For any other device, hardware logic could be used on the interface for translation purposes.
The roles of these devices is to down-convert the RF signal to baseband (direct conversion or low-IF), and digitize it to feed
the IQ samples to the SX1302 baseband chip.
The interconnection to the front-end device is organized as follows. Here, the SX1250 is taken as an example:
