Part Number: CC1120
Other Parts Discussed in Thread: WMBUS

Hello,

i will use the cc1120 in 433MHz Band with 9600 kBaud Symbol rate, 4-GFSK and 25kHz channel spacing.

I use Data whitening, PA Ramping and the FIFO Packet Mode.

Here my favorite Settings:

Now my Question:
What's the best Deviation for a robust Signal on this Symbol rate?

The examples for 4-GFSK are for faster Baudrates in SmartRF Studio.

Has anyone exerience with it?

I would suggest you use the same deviation as WMBUS Ng: 7.2 kHz since this has been tested.

A smaller deviation would give a very small modulation index for the inner symbols.
