In the previous example the various IF frequencies would be set as follow:
IF3-6 LoRa Channels
Multi-data rates
866.6
Radio A
867.4 MHz 868.0 868.8 MHz
Radio B
IF7-10 LoRa Channels
Multi-data rates
IF1-250 kHz fixed data rate
LoRa back-haul channel
IF2 64 kbit/sec
GFSK channel
If for example, 8 contiguous 125 kHz LoRa channels are
desired the following configuration may be used:
- Radio A PLL is set to 867 MHz
- Radio B PLL is set to 876.5 MHz
The two radio baseband spectrum overlap a little bit.
