Definitions

  • the present invention relates to an energy coupling device, usable in VHF and UHF.
  • Such devices are necessary in different cases: to, from a source, make several amplifiers or preamplifiers operate in an equipotential and equiphase fashion, or else to add up the powers delivered by several equipotential preamplifiers and equiphases in order, with the power obtained , to operate amplifiers in an equipotential and equiphase manner, or even to add up the powers delivered by several equipotential amplifiers and equiphases to supply the same user generally consisting of a transmitting antenna.
  • the object of the present invention is to obtain the same advantages as those linked to the embodiments with cascaded hybrid junctions, while minimizing the disadvantages.
  • a device for coupling energies between m energy sources, with m positive integer, and n users, n positive integer and m + n greater than 2, in which, for m greater than 1, the m sources are in phases and in which, for n greater than 1, the energies are supplied in phase to the n users, is characterized by a combination of m first and n second 90 ° 3dB hybrid circuits each having four ports, the first and the second access as well as the third and fourth access of each hybrid circuit forming pairs of conjugate accesses of m and n balancing loads and of a first and a second equipotential distribution box and equiphases with m inputs and n outputs, having the same input / output phase shift, ⁇ c, the combination being such that the m first circuits have their m first accesses respectively coupled to the m sources, their m second accesses respectively connected to the m loads, their m third ports connected respectively to the m inputs of the first box, their m fourth
  • FIG. 1 shows the diagram of a coupling device making it possible to supply an antenna A with the sum, to the nearest losses, of the energies supplied by n amplifiers, E1 to En, (in the example described n was equal to 8 and the amplifiers each had an output power of 1 kilowatt).
  • the outputs of amplifiers E1 to En are respectively connected to accesses 1 of n couplers to 3dB, D1 to Dn. Between the ports 2 of the couplers D1 to Dn and the earth, balancing resistors Rd1 to Rdn are mounted, which constitute suitable loads.
  • the ports 3 of the couplers D1 to Dn are respectively connected to the inputs 1 to n of a distribution box C1 with n inputs and an output; similarly, the accesses 4 of the couplers D1 to DN are respectively connected to the inputs 1 to n of a distribution box C2 with n inputs and an output; the C1, C2 boxes are equipotential and equiphase and even have input / output phase shift.
  • the outputs of the distribution boxes C1, C2 are respectively connected to the accesses 1 and 2 of a coupler to 3dB, B, whose access 3 is connected to ground by a balancing resistor Rb and whose access 4 is connected to antenna A, the latter comprising an impedance matching circuit, not shown.
  • the amplifiers E1 to En must deliver equipotential and equiphase signals; known arrangements exist to obtain this result, but it is also possible, as will be seen with the aid of FIGS. 2 and 3, to achieve this result with arrangements according to the invention since it involves, each time , to distribute the power of one or more sources to one or more users, these users becoming sources in the following amplifier step; thus the amplifiers of figure 1, which are the users of the energy of preamplifiers of figure 2, are also the energy sources for the user which is the antenna A of FIG. 1.
  • the assembly formed by the couplers and the distribution boxes of FIG. 1 constitutes a switch from the accesses 1 of the couplers D1 to Dn towards the access 4 of the coupler B when the accesses 2 of the couplers D1 to Dn and the access 3 of coupler B, are perfectly decoupled.
  • Installation according to the figure 1 operates as a power summator, the power on the access 4 of the coupler B being the sum, to the nearest losses, of the powers delivered by the amplifiers E1 to En.
  • the assembly according to FIG. 1 is reversible, with the amplifiers E1 to within.
  • FIG. 2 shows how the n amplifiers E1 and En are supplied from m equipotential preamplifiers and equiphases, J1 to Jm.
  • the assembly includes the m preamplifiers followed by m 3dB couplers, at 90 °, H1 to Hm, followed by 2 equipotential and equiphase distribution boxes, identical G1, G2 with m inputs and n outputs, followed by n couplers at 3dB, with 90 °, F1 to Fn, followed by the n amplifiers E1 to En. Between ports 2 of couplers H1 to Hm and ground as well as between ports 3 of couplers F1 to Fn and ground. balancing resistors Rh1 to Rhm and Rf1 to Rfn are connected.
  • the part of the assembly of FIG. 2 going from the preamplifiers J1 to Jn to the inputs of the distribution boxes G1, G2 corresponds to the part of the assembly according to FIG. 1 comprised between the amplifiers E1 to En and the inputs of the distribution boxes C1 and C2 ; the protection of the preamplifiers J1 to Jm against abnormal operation of one of them is thus ensured.
  • the part of the assembly of FIG. 2 going from the outputs of the distribution boxes G1, G2 to the inputs of the amplifiers E1 to En corresponds to the part of the assembly according to FIG. 1 between the inputs of the distribution boxes C1 and C2 and the outputs of the amplifiers E1 to En, that is to say a part used in the opposite direction to its use according to FIG. 1 by taking advantage of its reversibility.
  • This part of the assembly of FIG. 2 allows an equipotential and equiphase supply of the amplifiers E1 to En.
  • FIG. 3 shows how the preamplifiers J1 to Jm can be supplied in an equipotential and equiphase manner from a source represented by a single amplifier, N, on the input of which is applied a signal S.
  • the assembly comprises the amplifier N followed by a 3dB coupler, at 90 °, M, followed by 2 equipotential distribution boxes and equiphases, identical L1, L2 at one input and m outputs, followed by m couplers at 3dB, at 90 °, K1 at Km, followed by the m preamplifiers J1 to Jm.
  • the part of the assembly according to FIG. 3 comprised between the output of the source N and the inputs of the preamplifiers J1 to Jm corresponds to the part of the assembly according to FIG. 1 comprised between the antenna A and the outputs of the amplifiers E1 to En, and therefore used, thanks to its reversibility, in the opposite direction to its use according to FIG. 1.
  • This assembly allows an equipotential and equiphase supply of the preamplifiers J1 to Jm.
  • the invention is not limited to the examples described, it generally applies to the equipotential and equiphase supply of n users by m energy sources, with m and n positive integers and m + n greater than 2.
