My final year project is designing a power amplifier with a bias control network and an open loop power control system.
The system looks like that:
The 2-Stage PA looks like that:

Firstly, I'd like to focus on the 2-stage PA itself, disregarding the bias network and OLPC system.
I'd like to bias it in class AB.
My main goal is to maintain high efficiency.
How do I start?
What kind of simulations shall I run?
The PA should maintain an output power of 1W.
The input signal frequency is 5.8GHz.
I'd appreciate your guiding folks.
Thanks.
