Definitions

  • the present invention relates to a tunable matching network that can be coupled to a microwave line.
  • a tunable adaptation network is e.g. for a microwave line that couples high energy microwave energy into the plasma combustion chamber of a fusion reactor. Since the plasma combustion chamber represents a constantly changing load resistance for the microwave line and thus the generator generating the microwave energy is not damaged by reflections resulting from mismatching, the load resistance occurring in each case is to be transformed to the line wave resistance.
  • two tunable capacitances which are separated from one another by an exactly dimensioned transformation line length are coupled to the microwave line for this purpose.
  • the capacities are coordinated by a mechanically complex pneumatic device.
  • this arrangement is likely to be too sluggish in order to be able to carry out an adaptation with as little delay as possible.
  • a tunable matching network can be used not only for the described application, but whenever a changing load resistor is connected to a microwave line.
  • the invention is based on the object
  • the matching network can be tuned electrically without mechanically movable parts means that impedance matching with little delay is rapidly changing. Load resistance of a microwave line guaranteed.
  • Another advantage of the arrangement is that no transformation line is required between the two variable reactances of the matching network mentioned in the input.
  • Figure 1 shows an adaptation network in longitudinal section
  • FIG. 2 shows a perspective illustration of the
  • FIG. 3 is an equivalent circuit diagram of this adaptation network. 1 shows a longitudinal section and FIG. 2 shows a perspective representation of a tunable adaptation network which is coupled to a microwave line L.
  • the microwave line L is a coaxial line with the inner conductor L1.
  • the microwave line L is fed at one input by a generator G and is terminated at its opposite output with a changing load resistor ZL.
  • the T equivalent circuit diagram with the impedances ZI and Z2 inserted into the microwave line L stands for the matching network, which serves to transform the respective load resistance ZL to the line impedance.
  • the matching network has a first line L1 and a second line L2, each of which has one end in contact with the interrupted inner conductor L1 of the coaxial microwave line L.
  • the two lines L1 and L2 are connected to one another at the opposite end.
  • a third line L3 branches off from this connection point.
  • the lines L1, L2 and L3 are designed as strip conductors.
  • the outer conductor to the strip conductors L1, L2 and L3 is formed by the housing GS indicated by hatching, which is connected to the outer conductor of the coaxial microwave line L.
  • the plate-shaped inner conductors of the two strip lines L1 and L2 are covered on their mutually adjacent sides with ferrite layers F1 and F2.
  • the plate-shaped inner conductor is covered on both sides with ferrite layers F31 and F32. Instead of the ferrite layers Fl, F2, F31, F32 on the
  • the outer conductor GS of the three lines can also be coated with ferrite.
  • the lines L1, L2 and L3 are realized as coaxial lines.
  • the arrows drawn in FIG. 1 outside the adaptation network indicate that the two lines L1 and L2 are exposed to a magnetic field Ml and separately the third line L3 to a magnetic field M2.
  • Magnetic fields Ml and M2 can be changed independently of one another. With the magnetic field M1 acting on the ferrite-loaded lines L1 and L2, the electrical length of these two lines L1 and L2 can be varied. Regardless of this, the electrical length of the third line L3 can be varied by means of the changeable magnetic field M2 which acts on the ferrites F31 and F32.
  • the described arrangement of the lines L1, L2 and L3 actually represents two different line systems.
  • the one line system consisting of the first line L1 and the second line L2, together with the housing GS form a shielded two-wire line on which two wave modes exist Common mode and a push mode.
  • Push-pull mode is when the currents flowing in lines Ll and L2 are equal and opposite directions
  • common mode is when the currents flowing in lines Ll and L2 are equal and equally directed.
  • the second line system consisting of the line L3 and the housing GS, only the common mode can be propagated.
  • the ferrite material on lines L1 ' and L2 is arranged between the lines (see FIG. 1) and is therefore only effective for push-pull mode.
  • the push-pull impedance Zg of the lines L1, L2 is matched by the magnetic field Ml and the common-mode impedance Zs of the line L3 by the magnetic field M2.
  • the adaptation network In the event that the adaptation network is operated at very high powers, it is expedient to cool the lines L1, L2 and L3.
  • the heat loss generated in the ferrites F1, F2, F31 and F32 can be very effective and simple with the aid of cooling channels which run through the inner conductor and / or the outer conductor of the lines L1, L2 and L3 designed as strip lines or as coaxial lines.
  • a cooling channel designated by K is indicated in FIG.
  • the changeable magnet elder Ml and M2 are generated by controllable electromagnets.
  • permanent magnets can also be provided, which generate a static magnetic field of such strength that the ferrites are operated above their gyromagnetic resonance, where they have the lowest losses.
  • the use of permanent magnets and electromagnets has the advantage that only small currents are required to tune the ferrite-loaded lines, since thanks to the permanent magnets only part of the required Magnetization must be applied by the electromagnet. It is also advantageous that if the control current for the electromagnets fails, the power loss in the ferrites does not increase very much because the permanent magnets always keep the magnetization of the ferrites above the gyromagnetic resonance.

Abstract

Un réseau d'adaptation accordable peut être accordé rapidement et sans difficultés sur une impédance voulue. Le réseau d'adaptation comprend une première et une deuxième lignes (L1, L2) mutuellement reliées par une extrémité et dont l'autre extrémité sert à les coupler à une ligne à micro-ondes (L). Une troisième ligne (L3) part du point de connexion entre les deux autres lignes (L1, L2). Les première et/ou deuxième lignes (L1, L2), ainsi que la troisième ligne (L3), sont chargées de ferrite (F1, F2, F31, F32). Le ferrite (F1, F2) des première et/ou deuxième lignes (L1, L2) et le ferrite (F31, F32) de la troisième ligne (L3) sont exposés à des champs magnétiques séparés (M1, M2) modifiables indépendamment les uns des autres.
