Definitions
- the present invention relates to filtering devices in the microwave domain, of the type having a metal cavity with dielectric inserts.
- the invention particularly advantageously finds application for filtering in the field of telecommunications by satellites.
- Metal cavities have long been used for filtering hyper frequencies. Recent studies have shown that it is advantageous, in order to improve the electrical performance of the resonators constituted by such metal cavities, to charge them by dielectric inserts extending transversely in the cavity. In this respect, it is advantageous to refer to the following different publications:
- the dielectric inserts indeed make it possible to distance the strong electromagnetic fields from the metal end walls of the cavity, and therefore to confine the energy in the central part of the cavity.
- An object of the invention is to provide a filtering device of the type having a metal cavity with dielectric inserts, which makes it possible to solve this problem and which, moreover, has particularly satisfactory properties, in particular at high powers.
- the invention provides a filtering device comprising a metal cavity closed by two end walls extending transversely with respect to the axis of said cavity, as well as at least two dielectric inserts defining a resonator in said cavity, characterized in that it comprises at least one coupling iris which also extends transversely with respect to said axis.
- this device comprises two coupling irises distributed respectively over one and the other of the two end walls and which couple said cavity with metal waveguides superimposed on said end walls.
- it may include a coupling iris extending transversely between two resonators each defined between two dielectric inserts.
- FIG. 1 schematically illustrates another possible application for the invention
- - Figure 4 is a graph on which the intercavity coupling coefficient of the device illustrated in Figure 3 has been plotted, as a function of the length of the iris of this device.
- the coupling device illustrated in FIG. 1 comprises a metal cavity 1, which is of the cylindrical type.
- the metal guides 6a, 6b being guides of type G90 with a height of
