I need an amplifier circuit diagram for a 400 Mhz to 4 GHz high power amplifier please?

these are a nightmare even the circuit board will have capacitative effects that change the resonance
at those frequencies you dont need alot of power so as the other person asked what do you mean by high power ..
remember at 4 ghz the distance is line of site you wont get any more distance after the horizon..
for example at 2 m radio has a fair distance at 10 to 25 watts

good luck. Wide band amplifiers in the GHz range are very difficult to design. You can't use conventional components and wiring in that frequency range. Special PC circuits are needed, so you need an expert in PC stripline design.
How much power? very important question...
I spent a lot of years in circuit design, but I would hesitate to do this project. It would take special RF design software, special printed circuit design, expensive components, and months of design time (at least).
Better to buy one.

Here's a site that probably has what you're looking for

What do you mean by "High Power"? In general, you are not goint to be able to build an amplifier that covers that large frequency range as a single unit. You would need to use multiple amplifiers.
