I am looking for reference circuit designs for the spirit1 low power sub-GHz transceiver. The data sheet is limited and the design references is no longer on ST. Does anyone have more information about layout and setup?

[SJeff.1]

I have found modules for 433MHz band but I need to design a circuit for ~169MHz (VHF band).

I'm unsure of the matching circuit and which components to use.

Any help would be greatly appreciated.
