Definitions

  • the invention relates to a microwave coupler with coupling lines crossing in the area of bridges.
  • a coupler of this type is described, for example, in the article “Monolithic GaAs Interdigitated Cuppiers”, published in IEEE Transactions on Electron Devices, Vol. ED-30 (1983) Jan, No. 1, New York, USA, pages 29 to 32.
  • the invention has for its object to provide a coupler with improved electrical properties compared to known arrangements.
  • the figure shows a coupler with four coupling lines 1 to 4, which are connected to the gates (port) P1 to P4.
  • Port 1 is e.g. the input port, port 2 em coupled port, port 3 a through port and port 4 an isolated port.
  • the signal transmission takes place from port 1 to port 3 via the two parallel coupling lines 1 and 3, which couples with the coupling lines 2 and 4 running parallel to them between port 2 and port 4.
  • the coupling lines 1 and 2 as well as 3 and 4 cross one another over half their length, in that the coupling line 1 is led over a bridge 5 over the coupling line 2 and the coupling line 3 over a bridge 6 over the coupling line 4.
  • Via a further bridge 7, the coupling line 2 bridges the coupling line 3 at port 2 and via a bridge 8 the coupling line 4 is led at port 4 over the crossing coupling line 1.
  • the length of all four cable runs ie the coupling lines
  • the number of bridges in each cable run is also the same, i.e. Each bridge per cable run.
  • the joints of the coupling lines are also the same for all four ports, with regard to the number and the geometric shape.
  • the fact that the four coupling lines are identical results in excellent electrical properties in terms of coupling, phase response, isolation and reflection factor, which cannot be achieved with conventional couplers at high frequencies. In this way, couplers with approximately ideal electrical properties are obtained, which e.g. can be constructed in stripline technology.
