Definitions

  • the invention relates to a strip line coupler for integrated high-frequency circuits with a plurality of coupled strip conductor tracks in a spiral shape with a closely adjacent course, the length of which is divided into two coupler halves and each coupler half is applied to a dielectric substrate.
  • a coupler is known from US Pat. No. 3,999,150.
  • the invention has for its object to provide a simple stripline coupler with good insulation in its construction.
  • FIG. 1 shows a top view of one half of a coupler with a quadruple stripline structure.
  • the four conductor tracks L1, L2, L3 and L4 are applied on a dielectric substrate S1, for example Al2O3 ceramic on the front in strip line technology in a closely adjacent course to one another in a rectangular spiral shape.
  • the back of the substrate S1 is metallized over the entire surface.
  • metallized contacting areas 1 to 7 for contacting with connection elements (not shown in the figure) are applied, which, for example, with a pincer-shaped end region, enclose the substrate on the long side and rest in contact on the metallization areas.
  • the conductor tracks L1 and L3 are guided to the contacting area 1, the conductor tracks L2 and L4 via a connecting line 10 to the contacting area 3.
  • the line ends of the conductor tracks L2 and L4 are connected via the plated-through holes 8 and 9 and a connecting line 15 applied to the rear of the substrate within a recess 17 of the metallization.
  • the line ends located in the inner region of the spiral are plated through-holes 11, 12, 13 and 14 to the rear of the substrate S1, the entire surface metallization of the rear surface having a corresponding cutout 16 in the area of these holes.
  • the second coupler half is constructed in accordance with the conductor structure shown in FIG. 1.
  • the substrate S2 carrying the second coupler half is placed with its metallized side on the metallized side of the first substrate S1 and connected in a contacting manner (cf. the illustration in FIG. 2).
  • the outer ends of the conductor tracks are on the right-hand side and, in the same way as in the first half of the coupler, are led to the contacting areas 5 and 7.
  • a bundle is defined as the number of conductor tracks of the coupler. In the exemplary embodiment shown, these are four conductor tracks, but any other number is also possible. This distance s between adjacent conductor bundles is equal to the distance of the conductor paths within a conductor bundle.
  • Fig. 3 shows a schematic representation of a coupler with 2-fold stripline structure in a planar arrangement.
  • the two halves of the coupler are wound in a spiral Instead of back to back arranged planar, ie adjacent on the same side of a substrate S3, the back of which is metallized over the entire surface.
  • the conductor tracks L5, L6 and L7, L8 of the two coupler halves which are applied in a rectangular spiral shape, are wound in the same direction, counterclockwise in the exemplary embodiment.
  • the line ends located in the inner region of the spiral are connected to one another via bond connections 18, 19, this again taking place in such a way that the outer strip conductor L5 or L7 of one coupler half is connected to the inner strip conductor L6 or L8 of the other coupler half.
  • the total lengths of both strip conductors of the coupler are therefore the same.
  • the distance s between the two coupler halves is equal to the distance between the conductor tracks within a conductor track bundle.
