AI Technical Summary
Technical Problem
RF windows of the pill box type experience unwanted resonances known as ghost modes, which limit the operational bandwidth and degrade the quality of communication by increasing loss and generating heat.
Method used
The RF window design includes a disk-shaped part with a metalization layer, paired ring-shaped parts, a tube-shaped part, and restriction parts to prevent rotation, thereby eliminating ghost modes.
Benefits of technology
This configuration effectively eliminates ghost modes, improving the operational bandwidth and communication quality by reducing losses and heat generation, while also lowering production costs.

Abstract
A pillbox-type RF window having an input / output window in a microwave tube, the pillbox-type RF window includes a disc-shaped part having a metallization layer formed on an outer peripheral portion of a disc-shaped ceramic body; a pair of ring-shaped parts made of metallic bodies having substantially the same external diameters as the disc-shaped part, arranged to sandwich the disc-shaped part on both sides, and integral with the outer peripheral portion of the disc-shaped part; a tube-shaped part made of a metallic body having an internal diameter substantially equal to the external diameters of the pair of ring-shaped parts and the disc-shaped part, for holding the pair of metallic components and the disc-shaped part on an interior thereof;and a restriction piece to eliminate rotation between the ring-shaped pieces and the tube-shaped piece;
