Simone, the actual tx power depends on a lot of parameters, and it is not a simple setting. For one thing, it depends a lot on the actual signal you are generating. If you need a very specific output power, you need to calibrate your setup with a tool such as a spectrum analyzer.
In general, the 100 mW (or 20 dBm) is the max possible tx power. The gain will reduce that. Obviously, the noise figure is not relevant for Tx.
