Abstract: A helical cavity resonator filter utilizes varactor tuning diodes positioned within each helical resonator coil. The diodes are positioned along the longitudinal axes of the coils so as not to interfere with the non-axial electromagnetic fields of the cavities associated with each helical resonator coil.

Abstract: A helical resonator includes a helical coil with one end flared out and folded back over a portion of the cylindrical helix made by the coil to create a winding of opposite pitch superimposed over the cylindrical helix. As an alternative design, a resonator is formed of a helical coil of a first length connected to a helical of opposite pitch. This resonator inhibits a third harmonic resonance but re-resonates around the fourth harmonic. When this resonator is used in combination with a conventional helical resonator, the undesired re-resonances are suppressed.

Abstract: A microwave filter comprising within a conductive casing, a plurality of resonant transmission lines arranged parallel between opposed end walls of the casing, a plurality of shielding members each located between adjacent transmission lines, and a capacitive interstage coupling member disposed transverse to the transmission line. The interstage coupling member comprises a dielectric member and a plurality of conductive regions arranged successively thereon so as to establish capacitive coupling between adjacent conductive regions. Each transmission line is connected at one end to a side wall of the casing and supported at the other end by the dielectric member in electrical contact with a respective one of the conductive regions, whereby the interstage coupling between the transmission lines is provided by the capacitively coupled conductive regions.

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.
