Definitions

  • the invention relates to a device for the combination without r.f. power loss of two or more microwave transmitters running in parallel and with any power ratio.
  • a device according to the preamble of Claim 1 is known from PATENT ABSTRACTS OF JAPAN, vol.4, no.83 (E-15)[565], 14th June 1980; & JP-A-55 49 052 (MITSUBISHI DENKI K.K.) 08-04-88.
  • the object of the invention is achieved by the characterising features of Claim 1
  • the summing network according to the invention comprises a variable coupler the structure of which will be explained by means of the drawing.
  • the structure can be considered having four gates numbered as usual. With such a device, the powers available at the two input gates 1 and 4 are added such that their sum is available at one of the two output gates whereas the other output is zero so that - presuming that the ohmic losses of the device are negligible - the combination of the two powers is obtained without matching losses.
  • the variation of phase ⁇ of one of the signals and the coupling coefficient c have to be set appropriately as a function of the input amplitudes and of the relative input phases.
  • the diffused signals are:
  • the appropriate choosing of the values for ⁇ and c which represents a second degree of freedom, can be effected by monitoring the signal amplitude at the output 3 and by setting the values for ⁇ and c such that said signal may be kept at the minimum, ideally zero.
  • the principle of the present invention is to substitute the two mutually coupled wave-guides to which the above explained theory refers by a single structure having a circular section and behaving as in realty it were two guides, i.e. it permits the independent propagation of two polarized fields in two mutually orthogonal axes.
  • these two modes of propagation have to be coupled, i.e. a power exchange between both of them must be possible, the guide in question which is structurally unique but functionally double has to be provided with coupling members.
  • These coupling members consist of diametral asymmetries, e.g. P protuberances called irisses, or continuous or discontinuous projections. These diametral asymmetries may be realized by a continuous deformation of the guide section which would assume e.g. an elliptical shape.
  • Said wave-guides in the following will be called polarizers.
  • the presence of said asymmetries works such that the two fields are no longer independent.
  • the field component ⁇ propagating in the direction which unites the irisses propagates with a speed (i.e. has a certain phase constant) which is different from the propagation speed of the component ⁇ orthogonal to it (and which propagates with a different phase constant), so that after a time the two field components get out of phase.
  • Acting on this phase difference said two orthogonal fields are coupled and consequently power is trasmitted from one to the other.
  • the phase difference is set by varying the angle ⁇ which the irisses uniting diametral plane includes with the input direction of said two fields. To each rotation angle corresponds a certain coupling degree.
  • the present invention makes use of a second guide-wave segment with P asymmetries in order to analogously obtain a second regulation possibility and consequently a second degree of freedom.
  • the device comprises in combination successively a first section consisting of an orthogonal mode transducer (orthomode transducer) OMT 1, possibly a connection section SR 1 having a circular exit, a first rotative joint GR 1, a first polarizer P1 which can be rotated by means of a motor M1, a second rotative joint GR 2, a second polarizer P 2 which can be rotated by means of a motor M2, a third rotative joint GR 3, possibly a second connecting section SR 2 having a circular input, a second section consisting of an orthomode transducer OMT 2, a detector diode DR connected with an output of said second section OMT 2 in order to detect the undesired field component and to send monitoring data to a computer (not shown) which controls the rotation of said motors M1 and M2.
  • the segment incorporating said diode DR is closed by a convenient terminal.
  • Such a device is a variable means which by a computerized control circuit automatically matches to the power and to the phase of said two transmitters.
  • the structure is aperiodic and therefore has wide band and low losses.
  • the coupling realized in asymmetry as a rotative structure is much better, owing to the lack of sliding contacts, to the small surface extension of the structure and to the lack of resonance effects.
  • the two segments P1 and P2 have been determined polarizers because they actually behave as polarizers. In fact, looking e.g. at the first of them and supposing that its length is such that there is a phase difference of 90 o between the component ⁇ 1 and the component ⁇ 1 of the field and that the input field is linearly polarized, it can be ascertained that, varying the angle ⁇ 1 e.g.
  • the first polarizer P1 is followed by a second polarizer P2 the length of which is twice the length of the first polarizer P1 such that, if the first polarizer supplies a phase difference of 90 o , the second polarizer supplies a phase difference of 180 o .
  • the second polarizer P2 in practice the field components ⁇ 2 will have a phase difference which is 180 o more than that of the components ⁇ 2.
  • the second polarizer P2 can be considered a union of two polarizers having a phase difference of 90 o , i.e. a first segment receiving the linearly polarized field supplied by the first polarizer P1 and supplying at the output a circularly polarized field, and a second segment receiving at the input the circularly polarized field and supplying at the output a linearly polarized field.
  • Said second polarizer P2 can be rotated at any angle in order to align the direction of the output field polarization with any desired direction. In practice, such a polarization of double length at the output has always a linear field, however turned by an angle which is twice the angle by which said polarizer is turned.
  • the undersired component of the output field is monitored by means of a diode DR connected in the transversal branch of the OMT 2 output transducer and the reading executed by the diode DR is sent to a computer which, for subsequent attempts and by actuating the motors M1 and M2, individualizes the two rotations ⁇ 1 and ⁇ 2 which minimize and eventually nullify said undersired component.
  • this solution does not exclude the search by manual instead of automatic rotation.
  • the sensitivity of the regulation system is very high because it is based on the detection of a zero power at the non used output and on the detection of the maximum power at the used output.
  • the system can be extended to more than two transmitters, combining the added output of the first two transmitters with that of the third one and so on.
