HIGH-FREQUENCY MODULE Russian patent published in 1996 - IPC

FIELD: radio engineering. SUBSTANCE: high-frequency module has a case, finned radiators, heat pipe, superhigh-frequency members, zones of failed joint between case walls and the members filled with foam dielectric material, coaxial and wave-guide paths for external communication. The case has front and back radiators interconnected rigidly with columns, and a shell with a ring, with the shell being drawn onto the back radiator. The ring is squeezed against the back radiator with low contact thermal resistance. The radiators and the shell form through sealed rings closed sealed volume and all surfaces of module structure transfer heat to the environment. Finned radiator includes antenna reflector. Finns placed under the reflector are concentric being smaller in height as approaching the center, and are provided with radial slots. Using elastic-deformable members the superhigh-frequency members are placed on heat conductive base that is connected to the radiator through thermally controlled heat pipe. Wave guide paths are connected to wave guide flange on module case with thin- walled insertion piece with high thermal resistance. Foam dielectric material is used to fill zones with failed joint between case walls and the members. EFFECT: high efficiency. 4 cl, 1 dwg
