Abstract
A method and apparatus for suppressing the generation of passive intermodulation within passive devices. A dielectric sheet comprising dielectric material is placed between first and second conductive elements of the passive device. The second conductive element is then mounted to the first conductive element, thereby "sandwiching" the dielectric sheet between the first and second conductive elements. In this manner, a direct contact connection can not be formed at the junction of the first conductive element and the second conductive element. This absence of a continuous direct contact minimizes the opportunity for passive intermodulation products to be generated at this junction of the passive device.
