Of course I can. I can do anything. I can do absolutely anything. I'm an expert!

The current.also, The data sheet doesn't specify the internal resistance

The 2:1 ratio (20 & 10) confirms that the source Z is 50 ohms.
Note that it's Vpp. You'd need RMS for power. Complex waveforms can get a bit complicated.
To measure the power you'd need to know the voltage (easier) and current (a bit trickier). Also, if AC and complex impedance, then phase angle enters into it.
Can you provide more details?

Why use all this feeding a bridge rectifier and voltage regulator? Is the bridge compatible with 100 kHz? ...getting towards RF, diode speed. And did you include a filter capacitor? ...otherwise poor regulator.
What are you up to?
