I was looking for a powerful RF transmitter lately but I didn't find many. They are low power (< 0.5W) or expensive.
I have a little understanding of a regular 433MHz transmitter's schematics. It is so simple, I want know can I build an RF transmitter with that circuit with more transmitting power (for example 2W power). Or if it is not possible with that circuit, I want to know what makes it impossible?
Edit : I know about legal terms on radio transmitters, and I only want to know about technical limitations.
