Definitions

  • the present invention relates to a power divider for high-frequency signals, the a line branch consisting of two coupled branch arms has, the branch point of the two branch arms a first gate and the two free ends of the two branch arms a second and a third Power gate form and form between the second and the third gate ohmic resistance is switched.
  • Such a power divider constructed according to the Wilkinson principle is known from US 4,875,024.
  • the two interconnected branch arms of the line branch each have a length of a quarter of the operating wavelength of the power divider.
  • the characteristic impedance of the two branch arms is ⁇ 2Z 0 .
  • a power divider constructed according to this known Wilkinson principle which is designed for a frequency range above 10 GHz, has a relatively narrow bandwidth.
  • the invention is therefore based on the object of a power divider at the outset Specify the type mentioned, which has the widest possible operating frequency band.
  • each of the two branch arms of the Wilkinson principle Branch one or more open stub lines.
  • This simple Stub lines that are to be manufactured and require little space result in a considerable increase in the operating frequency band of the power divider.
  • a bandwidth of 65% can be achieved.
  • the operating bandwidth of the power divider can be further expanded be enlarged so that each of the three gates of the power divider with an input or output line is connected and that at least one of the input or Branch off one or more spur lines.
  • the Realize power dividers as MMIC (Monolithic Microwave Integrated Circuit).
  • the only figure in the drawing shows a power divider implemented in stripline technology, which is based on the Wilkinson principle.
  • This power divider essentially consists of a line branch with two coupled branch arms L1 and L2.
  • the branch point of the two branch arms L1 and L2 forms a first gate T1 of the power divider.
  • the free end of the branch arm Ll forms a second gate T2 and the free end of the branch arm L2 forms a third gate T3 of the power divider.
  • a signal fed in at the first gate T1 is divided equally between the two gates T2 and T3, or the powers of two signals fed in at the gates T2 and T3 add up at the gate T1.
  • an ohmic resistor R is connected between the two gates T2 and T3.
  • the resistance R has a value of 1.6 Z 0 , where Z 0 is the characteristic line impedance.
  • One of the two branching arms L1 and L2 branches in each case idling Stub line SL1, SL2 from.
  • These two stub lines SL1 and SL2 have one Operating bandwidth of the power divider increasing effect.
  • the length of the two Stub lines SL1 and SL2 is considerably less than ⁇ / 4 ( ⁇ is the middle one Operating wavelength of the power divider) and is selected so that the bandwidth of the Power divider is as large as possible.
  • the branch lines SL1 and SL2 branch approximately in the middle of the branch arms L1 and L2.
  • a further increase in the operating range is achieved by using the Gates T1, T2 and T3 connected input and output lines LT1, LT2 and LT3 are also provided with idle stub lines.
  • Deviating from the illustrated embodiment also only one or two of the three input or output lines LT1, LT2, LT3 Stub lines are provided.
  • There is also no need to Output lines LT1, LT2, LT3 two symmetrically arranged stub lines may be provided, under certain circumstances only one of the respective is sufficient Branch line branching off the input or output line.
  • the input and output lines LT1, LT2, LT3 act like series inductors, and those from the input and output lines LT1, LT2, LT3 branch lines LT11, LT12, LT21, LT22, LT31, LT32 act like Parallel capacities.
  • the input and output lines LT1, LT2, LT3 also form their stub lines LT11, LT12, LT21, LT22, LT31, LT32 adapter elements Low pass characteristic.
  • the length of the stub lines LT11, LT12, LT21, LT22, LT31, LT32 is smaller than ⁇ / 4 and dimensioned so that the widest possible bandwidth for the power divider.
  • the spur lines LT11, LT12, LT21, LT22, LT31, LT32 branches from the input and output lines LT1, LT2, LT3 in one Distance from approx. ⁇ / 8 to the gates T1, T2, T3.
