Abstract: A Yttrium Iron Garnet (YIG) tuned band reject filter using one or more Shunt YIG resonators provides for much wider minimum rejection bandwidths without increasing maximum 3 db bandwidths or spurious response. Various configurations of a tunable shunt YIG tuned band reject filter achieves a wide rejection bandwidth at the low end of the tuning range while keeping the maximum 3 db bandwidth, normally occurring at the high end of the tuning range, to a minimum.

Abstract: A highly compact band pass filter that has excellent mechanical strength is disclosed. A band pass filter according to the present invention employs a dielectric block of substantially rectangular prismatic shape constituted of a first portion lying between a first cross-section of the dielectric block and a second cross-section of the dielectric block substantially parallel to the first cross-section and second and third portions divided by the first portion and metal plates formed on surfaces of the dielectric block. The first portion of the dielectric block and the metal plates formed thereon are enabled to act as an evanescent waveguide. The second portion of the dielectric block and the metal plates formed thereon are enabled to act as a first resonator. The third portion of the dielectric block and the metal plates formed thereon are enabled to act as a second resonator. The metal plates include at least one exciting electrode formed on a first surface of the dielectric block which has the widest area. Thus a wide band characteristics can be obtained whereas the very thin dielectric block is used. Further, a high unloaded quality factor (Q0) can be obtained because the radiation loss is lowered when the thickness of the dielectric block is reduced.

Abstract: An electromagnetic filter includes a plurality of dielectrically-loaded split-ring resonators. The resonators are oriented side-by-side generally within a single plane to achieve side-coupling. The side-coupled orientation of the resonators allows adjacent resonators to be set apart at a distance to achieve electrical coupling. Both the side-coupled orientation of the resonators and the dielectric-loading result in significant volumetric reductions without detrimental decreases in the quality factor of the filter. Coupling screws disposed between adjacent resonators provide further control over the coupling between adjacent resonators.

Abstract: The inventive microwave filter is based upon the utilization of a prototype filter of known type, and a recognition of the properties of microwave C-sections, and parallel coupled line capacitance arrays. A prior art filter is chosen as a prototype filter and is partitioned into a general equivalent circuit derived by applying electrical constraints to the standard equivalent circuits for microwave C-sections and parallel coupled line capacitance arrays. A set of general equations is then written for the equivalent circuit, and by using the equations it is possible to design filters having a wide range of desired filter characteristics simply by substituting the values from the prototype filter into the equations. It is therefore possible to construct a wide variety of filters from a few standard parts. Strip line filters can also be made utilizing the general equations.

Abstract: The specification discloses a frequency selective or gain equalizing attenuator having a highly controllable profile of attenuation versus frequency of microwave energy propagated along a transmission line. Spaced a quarter-wavelength apart, a pair of resonant stubs are coupled to the line through resistive loss elements. Depending upon the frequency of the incident energy and the length of the stubs, the coupling of the lossy elements to the line varies as the stub reactance varies from short to open and, accordingly, provides a predetermined desired attenuation characteristic. The overall discontinuities on the transmission line caused by the stubs and lossy elements substantially mutually cancel each other because of their symmetry and quarterwave spacing along the transmission line. A full reading of the specification is recommended for details of the concepts involved.
