Abstract: A passive intermodulation (“PIM”) distortion test apparatus includes a housing, hammering elements disposed within the housing, each hammering element including a moveable striking member, a strike plate positioned above the hammering elements, where a bottom surface of the strike plate is positioned at a distance above the hammering elements such that the moveable striking members of the hammering elements impact the strike plate when moved into their activated positions, and a retaining member that is configured to hold a device under test on a top surface of the strike plate while a PIM distortion test is performed on the device under test.

Abstract: A resonant cavity filter includes a housing having a resonator therein, and a tuning element including an elongated pin member having a conductive outer surface. The tuning element is mounted for insertion of the elongated pin member into an interior of the resonator. The conductive outer surface includes a contact portion by which the elongated pin member is secured in a desired position to adjust a frequency response of the resonant cavity filter, where the contact portion is free of threading.

Abstract: The present invention provides target devices such as filter units with a plurality of external projection members that project outwardly from the target device and cooperate with apertures in a mounting bracket whereby the target device can be slidably moved from a first position to a second position provided by a lobe of the apertures to couple the target device to a respective support structure using a respective mounting bracket. The mounting bracket can be provided as a plurality of mounting brackets, including a first one attached to the support structure and a first side of a first target device and a second one attached to a second side of the first target device and to a first side of a second target device thereby allowing the first and second target devices to be stacked together to a common support structure.
