Definitions

  • the invention relates to a microwave ring hybrid according to the preamble of claim 1.
  • a microwave ring hybrid is known, for example, from Siemens magazine 48 (1974), supplement “News transmission technology", page 162, Figure 8.
  • connection arms are galvanically coupled, so that additional networks for galvanically decoupling the connection arms, such as chip capacitors or finger couplers, for example, must be additionally provided when using the ring hybrid for parallel connection of two amplifier modules. These additional components can disturb the symmetry and adaptation of the ring hybrid and thus cause reflections and losses.
  • the object of the invention is therefore to design the microwave ring hybrid according to the preamble of claim 1 so that all connecting arms galvanically ent from each other are coupled without the use of additional components. This object is achieved by the characterizing feature of patent claim 1.
  • the connecting arms of the ring hybrid are designated by the reference numerals 1, 2, 3 and 4. They are located on the top of the dielectric carrier substrate 5 and are designed as microstrip lines.
  • the ring 6 of the ring hybrid consists of a closed slot line on the underside of the carrier substrate 5.
  • the connecting arms 1, 2, 3 and 4 cross the ring 6 vertically in the coupling area.
  • connection arms 1, 2, 3 and 4 are distributed over the circumference of the ring 6, which has a circumference of 3/2 X as in a conventional 180 ° ring hybrid; ie the distance between two connecting arms - 1 and 3 - on the circumference of the ring 6 is 3/4 X and the other connecting arms - 2 and 4 - are each at a distance of ⁇ / 4 on the circumference of the ring 6 from adjacent connecting arms.
  • the one line ends of the connection arms 1, 2 and 3 protrude a ⁇ / 4 piece into the ring area and thus ensure a suitable transformation in the coupling area of the slot line and the microstrip line.
  • connection arm 4 which is preferably connected to an absorber, can be designed in various ways. Either both ends of the line on either side of the ring crossover can protrude into the ring area by one ⁇ / 4 line section or project outwards, or, as shown in FIG. 1, a line end can be extended by an X / 4 section from Ring area protrude outwards, whereas the other end of the line through a rivet 9 with the conductive layer 7, cf. Fig. 2, on the underside of the carrier substrates 5 is connected and thus forms an absorber. To compensate for series inductances of the absorber, the connection arm 4 is connected to a parallel capacitance 10 in microstrip technology on the side projecting into the ring area.
  • Fig. 2 the ring hybrid is shown in section.
  • the slot line 6 is embedded in the conductive layer 7.
  • the wave resistance of the microstrip line is preferably chosen to be 50 Q. For the slot line, this results in a wave resistance of 71 ⁇ .
  • FIG. 3 shows an exemplary embodiment for a 90 ° ring hybrid.
  • the connecting arms 1, 2, 3 and 4 are distributed on the circumference of the ring 6, which is designed in slot line technology, at a distance of ⁇ / 4.
  • the connecting arms cross the ring 6 again vertically.
  • the connecting arms 1, 2 and 3 also project into the ring area by one ⁇ / 4 piece each.
  • the wave impedance of the strip lines 1, 2, 3 and 4 is Z 0 , for example 50 Q.
  • the ring 6 using slot line technology on the underside of the carrier substrate 5 has slot lines with different widths.
  • the width b1 of the slot line is selected so that it has a characteristic impedance of 0 / ⁇ 2, for example 35Q.
  • the width b2 is chosen so that it has a characteristic impedance of Z o , for example 50 Q.
  • tuning elements can be attached in the area of the intersections.
