Hi, I want to reduce the power level of the attached circuit because this circuit is generating a lot of power than what actually required and I want the following requirements.
Power-400 Watt
Frequency-470KHz
Voltage-220Volt
Please suggest what should I do in order to design the circuit with above requirements and let me tell you that someone asked me use amplifier instead of DRF1400 IC will it work ??

Hello
If you want to generate less power, it is useless to use this circuit. It is not a good solution to use a large circuit and then use a small power.
Instead, you can build a small TX with a sinusoidal oscillator of a few mW or a few Watts, in my opinion.

I agree with @Giovanni Di Maria, this is an RC circuit designed to give high efficiency in high power applications.
