Abstract: A bandpass microwave filter (32) is constructed by use of a right cylindrical cavity resonator (10) wherein end regions (22, 24) of the resonator are tapered. The tapering is accomplished by replacing end portions of a right cylindrical sidewall with frusto-conic sections (22, 24) of side wall. Each frusto-conic section joins a central cylindrical section (26) of the sidewall with a planar end wall (14, 16). Each of the end walls is provided with a coupling slot (28, 30) having dimensions substantially smaller than a half wavelength of the center resonant frequency of the resonator so as to be a nonresonant slot. The slots in the end walls may be coupled to rectangular waveguides (34, 36) which form input and output ports by which electromagnetic signals are applied to and extracted from the resonator.

Abstract: The present invention discloses a microwave filter (10) for controlling the degenerate resonant modes of a spherical cavity resonator (12). The spherical cavity resonator (12) has an inner spherical surface (14) which defines a spherical cavity (16). A first and a second set of tuning elements (18) extend inward from the inner spherical surface (14) of the resonator (12) into the spherical cavity (16). One of the first set of tuning elements is located near an electromagnetic field peak, either a radial electric field peak or a surface magnetic field peak, of at least one of the degenerate modes for tuning a resonance thereof. One of the second set of tuning elements is located between electromagnetic field peaks, either radial electric or surface magnetic field peaks, of degenerate modes in at least one pair of the degenerate modes for intercoupling thereof.

Abstract: A microwave waveguide filter includes a main-line cavity structure with a group of at least two rectangular main-line cavities arrayed along a main propagation path and including a first main-line cavity and a second main-line cavity. Each main-line cavity includes a sidewall, and each pair of adjacent main-line cavities has a common transverse wall transverse to the main propagation path and a main-line aperture in the common transverse wall. A rectangular first feedback cavity is in microwave communication with each of the first main-line cavity and the second main-line cavity through the respective sidewall of the first main-line cavity and the second main-line cavity. There is a first-cavity feedback aperture between the first feedback cavity and the first main-line cavity, and a second-cavity feedback aperture between the first feedback cavity and the second main-line cavity.

Abstract: A microwave band pass filter for filtering electromagnetic signals has a set of cavities arranged serially, with a block of dielectric material filling each cavity to define regions of each cavity which are loaded with dielectric material and regions which are free of the dielectric material. Each cavity may be viewed as a resonator for a fundamental mode of progagation of an electromagnetic wave while each block can be viewed as a resonator for higher-order modes of propagation of electromagnetic power. The cavities are separated by walls having slots aligned with the free regions of the cavities for coupling power from the fundamental mode while minimizing interaction with power of the higher-order modes. The filter enables the construction of an enlarged passband while inhibiting the presence of the spurious higher-order modes in a stop band bordering the passband.

Abstract: A filter system is composed of two identical filters coupled between an input waveguide and an output waveguide to provide a 4-port directional filter characteristic operable with quasi-elliptic linear modes of electromagnetic propagation within each of the filters. Each of the filters may be constructed of a plurality of cavities arranged serially, one behind the other, with one of the cavities in each of the filters being employed for coupling electromagnetic power between the two waveguides. The coupling is accomplished by use of a transverse slot and a longitudinal slot in each of the waveguides, the slots extending through sidewalls of the waveguides into walls of the cavity in each of the filters for symmetric and antisymmetric coupling, respectively, of longitudinal and transverse components of a transverse electric wave in each of the waveguides. A phase quadrature relationship between components of a magnetic field coupled from the input waveguide is retained by the filters and, upon radiation via the slots into the output waveguide, results in the generation of an output wave in only one direction from the output waveguide, there being cancellation of a wave in the opposite direction from the output waveguide.

Abstract: A switchable dual mode directional filter system includes two identical filters coupled to input and output waveguides at the same plane in phase quadrature. Each waveguide has two ports through which the signal enters and exists. One of the filters has a switching device incorporated therein for selecting the desired output port. One embodiment of the switching device includes a pair of coupling members that extend radially inward within the cavity of the filter toward a central axis. These coupling members define two coupling positions for the system. Solenoids move the two coupling members into and out of the cavity of the filters. Only one coupling member is used at a given time. This switching device is designed to change the polarity of one of the components of the signal wave to change its wave characteristics in the output waveguide. As a result, the desired port of the output waveguide can be selected easily.

Abstract: An interface that provides minimum changes in contact pressure over a thermal range is disclosed. The interface is a mated joint of given material, typically metallic, joined by a mechanical fastener or fasteners. The fastener(s) create contact pressure at the joint surface wherein the contact pressure variation over a temperature range is minimized by the use of a thermal compensator having a predetermined length. The thermal compensator's length is chosen by setting the thermally induced expansion delta to offset an equal delta created by the fastener and interface configuration. The difference in expansion of the mated joint and fastener is canceled by the equal, but negative, difference between compensator and fastener. This cancellation of expansion minimizes the change in contact pressure at the joint interface. Maintaining a constant pressure provides PIM reliability during temperature changes.
