Abstract
An RF filter for improving PIMD performance includes: a housing having at least one cavity and a dielectric resonator held in the cavity; washers shaped as circular plates and made of metal that are joined to an upper and lower portion of the dielectric resonator; and a cover joined to the housing. A protrusion may be formed on one side of the washer to contact the cover or the housing, where the washer protrusion may increase in height along a direction moving away from the center.
