Hi All
The primary simulation of Envelope Modulator (for Envelope Tracking Power Amplifier) is always done with a fixed resistor as the dynamic resistance of PA and it's normally around 5-10 Ohm.
1) How may I find that approximate resistance to be assumed as the load of the Envelope Modulator? Is there any calculation, measurement, ...?
2) Why lower Rload is mostly preferred?
Thanks a lot for any hint, in advance
