BAND-PASS FILTER Russian patent published in 2009 - IPC H01P7/10 

FIELD: electronics.

SUBSTANCE: invention relates to super-high frequency engineering and allows for improving heat removal from the open disc-shaped dielectric resonators. The band-pass filter contains hollow metal screen with connectors to supplying lines being installed on the proper ends, n open disc-shaped dielectric resonators, where n is an integer number and equal to n≥1 and metal plates attached to the internal surface of hollow metal screen. The hollow metal screen takes away any beyond band energy transfer between input and output and ensures electromagnetic inter connection of open disc-shaped dielectric resonators. The holder for each open disc-shaped dielectric resonator is represented as three metal plates provided with grooves. So the open disc-shaped dielectric resonator is fixed to the said metal plates while the metal plates are attached to the internal surface of the hollow metal screen. Such arrangement ensures removal of heat in the required amounts from resonators to the screen walls. Therefore, the proposed by the invention band-pass filter may be used in dielectric resonators located as planar structure in beyond band screen cavity in high power channels (to 200 Wt).

EFFECT: improved heat removal from disc-shaped dielectric resonators.
