Hi folks,
I'm trying to design a 3 stage PA line up consisting of pre-driver, driver & a final PA. The predriver & driver stage has been designed & my focus now is to design the final PA that needs the following goals to be achieved:
1) Power= 1.8 Watt or 2 Watt
2) Frequency range= 806-870MHz
3) P1dB= 36dBm
Besides that, this PA line up is powered at 3.6V.
This is how it should look like:

The question that i would like to ask are:
1) What type of power combining techniques that i can consider to achieve these goal besides the impedance matching technique?
2) What type of power splitter techniques that i can use besides the impedance matching technique?
