Yes, I think so. If the frequency is high enough so that it's not the limiting factor the size would mainly depend on how much power you can dissipate in a given volume. The highest power RF amplifiers I've ever seen were the klystrons used for the LEP and ESRF accelerating cavities. Those were large in part because of the relatively low frequency of 350 MHz but I believe there was also a large water-cooled absorber that dissipated whatever power was left in the MW+ electron beam given the conversion efficiency. |
