The invention discloses an integrated type high-power high-density high-frequency transmission structure. The structure comprises a TR module and an antenna module, a cold board module, fuzz buttons, wherein the cold board module is fixedly connected between the TR module and the antenna module; a flowing channel for conveying a coolant is formed in the cold board module; and the fuzz buttons are distributed on the cold board module and are in communication with the TR module and the antenna module positioned on the two sides of the cold board module for transmitting a high frequency signal between the TR module and the antenna module. An integrated type high-power high-density high-frequency transmission scheme is realized in the invention, and the integrated type high-power high-density high-frequency transmission structure has the advantages of compact structure, light weight, small size, and low transmission loss.
