Definitions

  • the present invention relates to a monolithically integrated Interdigital coupler consisting of several parallel lines running side by side, whereby the End of each line with a conductive airlift a line that is not directly adjacent to it is connected.
  • the bandwidth of the coupler can be increased in that Connection lines at the gates of the coupler with stub lines be provided to avoid reflections at the gates as possible largely reduce.
  • Interdigital coupler one monolithically integrated on a substrate Interdigital coupler. It is a 3 dB coupler with four gates 1, 2, 3 and 4. The four gates 1, 2, 3, 4 are parallel over five adjacent lines 5, 6, 7, 8 and 9 see above coupled that a z. B. at gate 1 fed power divided equally between the two gates 2 and 4 gate 3 remains completely decoupled.
  • the five lines 5, 6, 7, 8 and 9 are as follows in known way (as with a "Lange coupler") with each other coupled and connected to the individual gates 1, 2, 3 and 4:
  • the two lines 5 and 7 are connected to the gate 1.
  • line 6 lies between the two lines 5 and 7, which ends in front of gate 1 and is connected to gate 3.
  • the line 7 is both with the gate 1 and with the gate 4 connected.
  • Line 8 is connected on the one hand to gate 2 and ends on the other hand in front of the gate 4.
  • the directly with the line 8 adjacent line 9 is at one end with the gate 4 in Connection and is open at the other end. This way and In this way, an interdigital interlocking pipe system is created, where lines 5, 6, 8 and 9 each an open one not connected to one of the gates 1, 2, 3 or 4 End.
  • the two outer lines 5 and 9 end approximately in the illustrated embodiment half the length of the coupler.
  • the free ends of the lines each via conductive Airlifts with a line that is not directly adjacent contacted. So there is between the free end of the Line 6 and line 8 an airlift 10, between the free end of line 5 and line 7 one Airlift 11, between the free end of line 9 and the line 7 an air bridge 12 and between the free End of line 8 and line 6 an air bridge 13.
