hiiiiiiiii all,
i am working on MICS band application , and I have to design a Power amplifier that can deliver 500 uwatt power to antenna(50 ohm).
i have gone through some IEEE paper and i found that most of them were using Class AB power amplifier which is driven by a self biased inverter. and it is also mention that they are using that self biased inverter to reduce second harmonics and they are using that as a buffer.
i have attached the circuit diagram below.
please help me in finding out
1. How that self biased stage is working (that means is it a buffer stage or an pre-amplifier stage).
2.How it reduces the second harmonics.
If anyone provide me some study material then i am really thank full.
