2.2 RF topology design recommendations and BOM

The BOM is primarily optimized for 345MHz, but some configuration is still required at 433MHz.

This BOM allows 12dBm at 345MHz and 433MHz. When operating at 345MHz, the LPF could always be made more stringent, but this would begin to reduce output power at 433MHz. If you add the LPF to 345MHz, the output power at 433MHz will drop to about 8dBm, but the harmonics in both bands will improve, especially 345MHz.
