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 else to add up the powers delivered by several equipotential amplifiers and equiphases to supply the same user generally consisting of a transmitting antenna.
  • this solution is ideal, but in practice it has various drawbacks such as power limitation, selectivity and relatively large losses in the circulators; - Hybrid junctions of the ring type, 3dB couplers, etc., have been cascaded, the amplifiers being connected two by two on such a junction; excellent decoupling is thus achieved between the amplifiers but, especially for a large number of amplifiers, this solution is expensive because of the number of hybrid junctions required and, moreover, the losses are significant; - distribution boxes have been associated with Wilkinson type protection devices; it is a pretty good solution but the realization in decimetric band for a large number of amplifiers, is very difficult.
  • 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 is characterized by a combination of m first and n second circuits. 90 ° 3dB hybrids, each having four ports, the first and second ports as well as the third and fourth ports of each hybrid circuit forming pairs of conjugate ports of m and n balancing loads and a first and second equipotential distribution boxes 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 coupled respectively to the m sources, their m second ports connected respectively to the m loads, their m third ports connected respectively to the m inputs of the first box, their m fourth ports connected respectively to the m inputs of the second box, that the n second circuits have their n first ports connected respectively to the n outlets of the first box, their n second
  • 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 if the energy sources for the user that is the antenna A of figure 1.
  • ⁇ c is the phase change resulting from the crossing of boxes C1 and C2
  • the signals on ports 1 and 2 of coupler B are respectively of the form: U / ⁇ 2. exp (j ⁇ c) U / ⁇ 2. exp-j ( ⁇ / 2 - ⁇ c) which gives, respectively on accesses 3 and 4 of coupler B U / 2.exp (j ⁇ c) + U / 2.exp-j ( ⁇ - ⁇ c) zero signal U / 2.exp-j ( ⁇ / 2- ⁇ c) + U / 2.exp-j ( ⁇ / 2 - ⁇ c) signal representing the total recombined power.
  • 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.
  • the assembly according to Figure 1 therefore provides perfect protection of the amplifiers against any imbalance and even against any complete stop of one or more amplifiers. And the ratio of the total power normally available to the total power actually available is, at losses near the system, as for a combination of cascaded couplers: n2 / (nn ′) 2 where n is the number of amplifiers out of order.
  • FIG. 2 shows how the n amplifiers E1 and En are supplied from m equipotential and equiphase preamplifiers, 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 with 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.
