Hi, I need to design a power amplifier for a RF transmitter and I am not sure how to start. I have the VCO built and I was told that the output of the VCO needs to go to the power amplifier. I was also told that a class AB amplifier is a good topology but I am not sure how to build this. I googled it and theres so many different class AB and i dont know which is correct. Also, would the VCO connect to the gate of the PA transistor? I need to have 15 db gain, -10db output matching, decent linearity and output power, and 2.35 to 2.55GHz operating frequency. Any help would be greatly appreciated, thanks.
