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.

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: 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.
