As I am re-designing this circuit called 13.56 MHz, Class-D Half Bridge, RF Generator with DRF1400, the information about this circuit can be obtained from internet .The problem in this circuit is that the power is 1.7KW which is so high therefore I want to reduce the power level up to 140W how it can be done .Also I want to reduce frequency of this circuit up to 5MHz from 27.56MHz how it can be done .Also give me an idea that how the PCB layout can be done because it is high frequency board therefore it comes under RF design ??

What circuit you are re-designing? You may need to provide some details, I am not sure otherwise how people may help to optimize your circuit - they may need to see at least the parts of circuit which you would like to optimize.

Please explain "... I am re-designing this circuit called 13.56 MHz, Class-D Half Bridge, RF Generator with DRF1400...I want to reduce frequency of this circuit up to 5MHz from 27.56MHz .."

It's difficult to understand what it is you want.

Perhaps instead of explaining how you want to change a circuit, explain what it is you are trying to achieve with the design once it is finished. What do you plan to do with the modified circuit?

Keep in mind that this forum is about using Altium, not radio design. Not all of us are radio experts.

And why not simply use FETs (Si, SiC or GaN) and normal (half) bridge drivers?
