Definitions

  • the invention relates to a phase shift combiner for electromagnetic waves.
  • phase-shifters are produced from line sections or from a hybrid coupler of which two accesses are provided with short-circuited lines.
  • the object of the invention is to overcome the drawbacks highlighted above.
  • the invention provides a phase shift combiner for electromagnetic waves according to claim 1.
  • the principle of the phase-shifting combiner according to the invention is simple and its implementation easy.
  • a microwave switch can be produced by considering, as shown in FIG. 2, two phase shifters according to the invention 20 and 21 whose inputs are connected to the outputs of a first hybrid coupler 22 and whose outputs are connected to the inputs of a second hybrid coupler 23.
  • phase shifter (20, 21) The insertion between the two hybrid couplers 22, 23 of a phase shifter (20, 21) on each link provides the phase variation to two states whose bandwidth is widened by the offset of the two phase shifters 20 and 21.
  • the action on the permeability ⁇ r or the permeability ⁇ r of the medium provides the state of the outputs.
  • a cell 14 is used in which one of the two inputs or one of the two outputs is connected to a suitable termination R .
  • n cells 14 as represented in FIG. 3 for example, makes it possible to produce a multiplexer with n + 1 inputs represented in FIG. 5, which by application of the principle of the reciprocity of any passive element is a demultiplexer with n + 1 outputs.
  • a double loop combiner with two inputs and one output such that this combiner comprises a hybrid input coupler 30 and a hybrid output coupler 31, two phase shifters according to the invention (32, 33 and 34, 35) being arranged in cascade respectively between the first output of the input coupler 30 and the first input of the output coupler 31 and between the second output of the input coupler 30 and the second output coupler input 31.
  • the two half-shells are assembled, in the plane of the figure, by screen-printed deposition of solder paste.
  • the half-shell 40 shown has bosses 41 which correspond on the other shell to tuning screws. On each of the loops 37, 38 is disposed a quartz blade of agreement 42, 48.
  • the two loops are made of INVAR to guarantee temperature stability.
  • FIG. 8 Another possible embodiment is illustrated in FIG. 8, where, unlike FIG. 6, only one phase shifter (32, 34) according to the invention is used on each channel.
  • the signal represented in FIG. 10 is then obtained, which illustrates the recombination of the first input E1 towards the output S.
