Definitions

  • the invention relates to an R switch for switching connections between microwave waveguides on and off according to the preamble of the main claim.
  • the R switch according to the invention with the characterizing features of the main claim has the advantage over the other that it is designed in several stages simply by a web-like design of the straight passage designed as a step transformer, and recesses are incorporated in the step transformer on both sides of the last step.
  • the measure according to the invention for increasing the bandwidth is very simple and inexpensive to manufacture using a milling machine.
  • recesses on both sides of all the stages are incorporated in the stage transformer of the straight passage, whereby a further lowering of the lower frequency limit of the R switch according to the invention is possible.
  • web-like designs are formed in several stages in the step transformers of the curved paths, and recesses are incorporated on both sides of the last step of the step transformers.
  • the measure according to the invention for increasing the bandwidth is very simple and inexpensive to manufacture using a milling machine.
  • the straight passage is designed as a step transformer in order to save material and weight by omitting the step transformers in the curved paths, insofar as this allows decoupling.
  • FIG. 1 shows a sectional view along the line SS in FIG. 2 through an R switch according to the invention with a first web-like configuration of a step transformer in the straight passage of the rotor
  • FIG. 2 is a front view of the straight passage of the rotor of FIG. 1 in the direction A,
  • Fig. 3 shows a cross section along the line LL in Fig. 4 by an R switch with a second web-like configuration of the step transformer in a straight passage and
  • FIG. 4 shows a front view of the straight passage of the rotor according to FIG. 3 in direction B
  • Fig. 5 is a sectional view along the line SS in Fig. 6 by an R switch according to the invention with a first web-like Design of a step transformer in a straight passage and / or the curved paths of the rotor,
  • FIG. 6 is a front view of the straight passage or the curved paths of the rotor according to FIG. 5 in the direction A,
  • FIG. 7 shows a cross section along the line LL in FIG. 8 through an R switch with a second web-like configuration of the step transformer in a straight passage and / or curved paths
  • Fig. 8 is a front view of the straight passage or the curved paths of the rotor of FIG. 7 in the direction B and
  • Fig. 9 is a sectional view along the line SS in Fig. 2 by an R switch according to the invention with a first web-like configuration of a step transformer in the straight passage of the rotor.
  • R switch 1 shows the transverse sectional view of an R switch 1, which consists of a stator 2 with end openings 3 to 6 for connecting waveguides (not shown in the figure) and a rotor 7 rotatably arranged in the stator 2 with a central straight passage 8 and on both sides of it there are “curved” paths 9 and 10, the ends of which lie parallel to axes 11 and 12 which are at right angles to one another.
  • These axes 11 and 12 also represent orientations of the waveguides to be connected to the R switch 1 after the position of the rotor 7, different waveguides fastened to the openings 3 to 6 of the stator 2 are switched through Position of the rotor 7, the openings 4 and 5 and the openings 3 and 6 are interconnected.
  • Rotating the rotor 7 clockwise by 45 ° connects the openings 3 and 5 to one another. Turning the rotor 7 clockwise by a further 45 ° switches through the waveguides connected to the openings 5 and 6 and the waveguides connected to the openings 3 and 4. If the rotor 7 is rotated 45 ° clockwise again, a passage is created between the openings 4 and 6. And a further rotation of the rotor 7 by 45 ° clockwise again results in the arrangement according to FIG. 1.
  • the stator 2 essentially has the shape of a cuboid and the rotor 7 has the shape of a cylinder.
  • the passage 8 and the paths 9 and 10 are designed as step transformers 13, 14, 15, which in particular requires the space required by the middle ones Parts of the passage 8 and the paths 9 and 10 is reduced.
  • the passage 8 like the paths 9 and 10, has a rectangular cross section, so that the side walls of the step transformers 13, 14, 15 have the shape of step steps.
  • the front view of the straight passage 8 in the direction A according to FIG. 2 consequently shows the front surfaces of the steps 16 to 19 of the step transformer 14.
  • the upper steps 17 and 18 of the step transformer 14 have the shape of narrow webs, which is achieved by milling recesses 10 to 23 on both sides of the steps 17 and 18, which in FIG Fig. 1 are drawn as undercuts by means of dashed lines 24 and 25.
  • a rotor switch has the disadvantage that the passage or path which does not connect any stator openings to one another acts as a cavity resonator which is supplied with energy via the inevitable gap between rotor 7 and stator 2. 1, the straight passage 8 thus acts as a cavity resonator.
  • the lower limit frequency is determined by the resonance frequency of the straight passage 8 and the upper limit frequency by the resonator frequency of the curved paths 9 and 10 (here, for example, when the rotor 7 is rotated 45 ° clockwise if the paths 9 and 10 are not active) educated.
  • the resonance frequency of the straight passage 8, which acts as the lower limit frequency of the R switch 1 can be considerably reduced in a very simple manner in order to increase the bandwidth of the signals that can be transmitted by the R switch 1 without errors that the Step transformer 14, as shown in FIGS. 1 and 2, is at least partially formed in the form of a web in that recesses 20 to 23 are milled away to the side of steps 17 and 18.
  • the bandwidth could be expanded to 17.7 to 22 GHz for a specific R switch called WR51 switch, which has a bandwidth of 19 to 22 GHz without the step-like design of the step transformer.
  • WR51 switch which has a bandwidth of 19 to 22 GHz without the step-like design of the step transformer.
  • the satellite band extends from 17.7 to 22 GHz, so that the WR51 switch after a modification according to the present invention can be used without problems for switching signals lying in the satellite band.
  • FIG. 3 An embodiment of the measure according to the invention for increasing the bandwidth of an R switch is shown in FIG. 3 in section along line LL drawn in FIG. 4 and in FIG. 4 as a plan view in direction B of the sectional view shown in FIG. 3.
  • FIG. 4 shows that, in contrast to FIG. 2, recesses 26 to 29 are milled out of the step transformer 32 not only to the side of the steps 17 and 18, but also to the side of the steps 16 and 19. 3, this is indicated by the dashed lines 30 and 31.
  • the advantage of this is a further reduction in the resonance frequency of the straight passage 33, which is, for example, inactive according to FIG. 3 and acts as a cavity resonator, and thus a further reduction in the lower cut-off frequency of the R switch 34.
  • the structure and mode of operation of FIGS. 3 and 4 R switch shown identical to the structure and mode of operation of the R switch shown in Figures 1 and 2, so that it will not be discussed again.
  • FIGS. 5 to 8 Further refinements of the measure according to the invention for increasing the bandwidth of an R switch are shown in FIGS. 5 to 8.
  • the advantage of this configuration is the lowering of the lower resonance frequency of the curved paths when these are switched inactive by a rotation of the rotor and thus act as cavity resonators.
  • the structure and mode of operation of the R switch are otherwise identical to those of the R switch according to FIGS. 1 to 4.
  • FIG. 5 corresponds to FIG. 1 and additionally has recesses 51, 52, 53, 54 as shown in FIG. 6 in the stages 48, 49 in the stage transformers 13, 15 in the curved paths 9, 10 which are shown in FIG. 5 are shown as undercuts by means of dashed lines 39, 40, 41 and 42.
  • FIG. 7 corresponds to FIG. 3 and additionally has recesses 55, 56, 57, 58 as shown in FIG. 8 in the steps 47, 48, 49, 50 in the step transformers 35, 36 in the curved paths 37, 38 7 by means of dashed lines 43, 44, 45 and 46 as undercuts.
  • Fig. 9 corresponds to Fig. 1, but the crooked paths 9, 10 do not include step transformers.

Abstract

L'invention concerne un commutateur R comportant un stator (2) et un rotor (7) avec trois chemins (8, 9, 10), dont le passage droit central (8) se présente sous la forme d'un transformateur étagé (14). Ce transformateur étagé a une forme de filet qui lui est conférée par des évidements (20, 21, 22, 23) ménagés dans ses étages (17, 18), cela pour que la limite de fréquence inférieure des signaux haute fréquence transmissibles soit abaissée.
