Yes, all parameters are with the matcing network in place.

Thanks a lot. I thougnt it's difficult to calcurate too.

I have another question, these specifications are including machting network loss?

This is not easy to answer. The radio won't work without the matching network, so it's not easy to measure the ouput power with and without the matching netwotk to calculate the difference. The inout (chip side) is not 50 ohm and it's differential, so it's not trivial to measure the loss either. The device is designed to operate with the matching network, it's part of the design. There will be some loss, but how much is hard to say. 2 dB if I may guess.
