Title:
HIGH-FREQUENCY INPUT COUPLER
Document Type and Number:
Japanese Patent JP2023019528
Kind Code:
A
Abstract:
To provide a high-frequency input coupler that can prevent a gap from being generated between a dielectric substrate and a high-frequency window structure.SOLUTION: The high-frequency input coupler is installed between a waveguide and an acceleration cavity and inputs a high-frequency wave from the waveguide to the acceleration cavity. The high-frequency input coupler includes an inner conductor, an outer conductor provided around the periphery of the inner conductor, a high-frequency transmission window structure having a high-frequency transmission window, and a dielectric substrate provided on a high-frequency input side of the high-frequency transmission window. The dielectric substrate is fixed to the high-frequency transmission window structure by brazing.SELECTED DRAWING: Figure 1
