- the Dielectric insert 2 consists for example of a dielectric ceramic with a high Dielectric constant of, for example, 10 to 50th
- Dielectric insert 2 consists for example of a dielectric ceramic with a high Dielectric constant of, for example, 10 to 50th
- clamping body 3 Between an outer periphery of the dielectric insert - here between cylinder jacket and waveguide 1 - are several Clamping body 3 is provided, which radially to the clamping body. 3 run in and only touch it tangentially.
- the clamping bodies 3 are made Quartz rods, which are preferably uniform in one plane are distributed and by threaded screws 31 in the waveguide first delivered towards the dielectric insert 3 out can be to the desired clamping pressure as well as the desired position (here center position of the dielectric Use in the waveguide 1) set.
- the desired clamping pressure as well as the desired position (here center position of the dielectric Use in the waveguide 1) set.
- the desired position here center position of the dielectric Use in the waveguide 1 set.
- a Support device 4 is provided for fixing the dielectric insert 2 in one Direction (here z-direction), by the / the Fixation direction / s (here x, y direction in a Transverse plane of the waveguide) of the dielectric insert 2 deviates by the clamp body 3 .
- This support device consists in the embodiment shown of two plates 41st and 42, wherein a plate 41 on a shoulder 5 in Waveguide 1 rests, the diameter jump in Waveguide represents.
- Another plate 42 is located on the opposite top surface of the cylindrical dielectric insert 2.
- the latter plate 42 is a Assigned clamping device 6, z. B. in the form of a Madenklemmschraube, by means of which the plate 42 in the direction the plate 41 is deliverable.
- the support device 4 is thus the dielectric insert in the z-direction fixable.
- the upper plate 42 may be omitted.
- the plate (s) 41 and 42 respectively preferably also made of quartz for thermal reasons.
- the plates 41 and 42 preferably have no Centering devices, such as steps, webs, etc., the to could lead to unfavorable thermal stresses.
- FIG. 2 shows a cross section through the circular waveguide 1 with a modification for the clamp body 3.
- Two of the Clamping body 31 and 32 consist of vertically in the waveguide first standing plates preferably made of quartz or ceramic, the Touch the dielectric insert 2 tangentially.
- the third Clamping body 33 consists as before of a rod, which means a screw on the dielectric insert deliverable is and to set the necessary clamping pressure suitable is.
- Figure 3 shows a to this Embodiment associated longitudinal section.
- the clamping body 3 consist of circular cylinders or balls, by means of grub screws radially toward dielectric Insert 2 are deliverable. Also in this Embodiment touching the clamp body 3 the Circular cylinder - or spherical designed dielectric insert 2 - only tangential.
- the Support device 4 from at least one other There are clamping body, which is suitable, a clamping action on the dielectric insert 2 in an axial direction to be determined by the orientation (s) used to fix the dielectric insert 2 by the clamping body 3 differs.
- the dielectric insert 2 is here is also cylindrical, mechanically rigid relative to the support device - plate 41 - fixed.
- the Plate 41 is at its outer periphery in a holder 8, which is attached to the inner edge of the waveguide 1, stored.
- the fixation of the insert 2 on the plate 41st is areal, for example, via a suitable Glue 7 with good thermal conductivity.
- the plate 41 consists of an electrically poorly conductive material which preferably good heat-conducting. As materials for this suitable are diamond or sapphire.
- Both by the planar fixation as well as by the good thermal conductivity Plate 41 can be a good heat transfer from the dielectric Insert 2 to the waveguide outer wall / Resonatorwand done and thus the loss energy generated in the dielectric be dissipated quickly.
- the paragraph 5 be used in the waveguide 1 against which the plate 41st is pressed by means of a clamping device.
- Clamping device are not suitable, for example metallic screws 61, 62 made of plastic, which in one Angle of about 45 ° are guided in the waveguide wall 1 and Press the plate 41 against the heel 5.
- the Support device 4 from a further plate 42, the in particular adhered to the dielectric insert.
- the Plate 42 may be with a similar holder as before be provided.
- additional clamping body 3 in Shape of pins, cylinders, etc. from good heat-conducting but electrical poorly conductive material such as diamond or Sapphire tangential to the outer shell of the insert 2 can touch, can be provided for further heat dissipation.
- these clamp body with the use of 2 glued thermally conductive.
- the Plate 41 and / or the plate 42 at its outer edge with be solderable material coated such that the plate 41 and 42 to the paragraph 5 and / or to the waveguide inner wall is solderable.
- the dielectric insert 2 soldered to the plate 41 and 42, respectively if a corresponding metallization takes place beforehand is.
- At least one of the clamping body 3, the support device 4, the waveguide inner wall, the dielectric insert 2 and / or the further clamping body can be connected to a superconductor completely or partially coated. In this way it is possible to reduce losses and the resonator quality increase.
- the waveguide resonator arrangement according to the invention can be built up filter structures, for example by Stringing together the aforementioned structures in one Waveguides. It can be especially synonymous Build up multi-mode filters that are suitable as channel multiplexers are. Since the attachment of the support device or Plate / n only over the waveguide wall in Waveguide propagation direction (z-direction) is done a resonator coupling / tuning in the z direction undisturbed possible.
