Hi guys, I'm a new member of this forum. As a chemist, I don't have much knowledge of electrical engineering, and that's the reason why I'm here. Hope you guys can help me out. I'm going to go straight to the point. I need to build a capacitor connected to an AC generator with an AC frequency of around 2 GHz (and more). I also need a power from 800W to a few kW. What do I need in order to do so? Like electronic oscillators or stuff like that? If you need any further information, please just ask. Thanks in advance.
