Hi,
I posted in another thread the following design of a PA:
View attachment 68001
IREF, VB (3.5V) and VDD (3.5V) Ports are DC signals.
IN Port is the input power (up to 0dBm).
What is the first stage role?
Is it correct to say that the power is being amplified only at the second stage?
Thank you very much.
