Definitions

  • the desired resonant frequency, on which the ring resonator is to oscillate for filtering out a narrow frequency range must be set very precisely.
  • Such printed ring resonators generally have variations in material and manufacturing tolerances, especially at higher frequencies, since the small dimensions of the ring resonator production tolerances have a greater impact. Therefore, a printed ring resonator usually does not have the exact desired resonance frequency after its production. It must therefore take place later a balance of the resonant frequency, although the quality of the resonator may only slightly deteriorate, because for the electrical properties of the oscillator and the filter as high as possible quality of the resonator is very important.
  • From DE-A-2 118 309 is a method for lowering the resonant frequency of microstrip resonators in microwave integrated filter circuits in which the width of the band conductor serving as a resonator is locally reduced by cutting slots in the band conductor with a laser.
  • the line material can be removed in any small portions. Because of this balancing method, it becomes possible to allow larger manufacturing tolerances and variations in the material parameters, whereby a significant cost reduction can be achieved. Due to the laser alignment, the geometric structure of the resonator is only slightly changed, which is why the resonator quality is reduced only insignificantly; because for use with oscillators and filters the highest possible quality is required. According to the invention, the width of the strip line coupled to the stripline ring is reduced by material removal at one or more points.
  • a laser additionally removes conductive material at one or more points of the stripline ring until the desired resonance frequency is reached.
  • line material is removed at points of the strip line ring where current maxima occur, when the resonance frequency is to be lowered, or at points at which current minima occur in order to increase the resonance frequency.
  • the conductor material is expediently removed in the form of a slot tapering the conductor width of the stripline ring, with a coarse adjustment being made over the depth of the slot and a fine adjustment of the resonance frequency over the width of the slot.
  • the stripline ring 1 of a ring resonator 1 is shown.
  • To tune the resonant frequency of this ring resonator is removed at the outer edge by means of a laser line material in the form of a slot 2.
  • the tapering of the conductor width caused by this slot 2 acts like a series inductance inserted in the resonant circuit.
  • the depth t of the slit 2 made by the laser has a larger influence on the resonance frequency than the width w of the slit 2. Therefore, a coarse adjustment is made over the depth t of the slit 2 and a fine tuning of the resonance frequency over the width w of the slit 2.
  • While the slot 2 is recessed on the outside of the stripline ring 1, a slot 3 can also be provided on the inside of the stripline ring 1.
  • a plurality of slots can also be provided on the inner and outer sides of the line ring 1. Placing the slit (s) in places of current maxima, this lowers the resonance frequency. If one chooses locations for the slit (s) at which current minima occur on the stripline ring 1, this leads to an increase in the resonant frequency.
  • the material removal for changing the stripline geometry can also have other shapes than laterally introduced slots 2, 3.
  • certain surface elements could be removed from the interior of the stripline ring 1.
  • the tuning of the resonant frequency of a ring resonator according to the invention is characterized in that with a stripline ring 4, a stripline 5 is coupled, whose width is changed at one or more points by a material removal with a laser.
  • the strip line 5 has been shortened by a piece 6 of length 1 or according to the invention has been narrowed by a slot 7 in the coupling region with the stripline ring 4.
  • material can also be removed at one or more points of the stripline ring 4 in order to match the resonant frequency of the ring resonator, as shown in FIG.
  • a varactor (capacitance) diode 8 is connected to stripline 5, then the resonator can be electronically detuned via a control voltage U.
  • the tuning slope can be achieved by targeted material removal e.g. be made constant at the points 6 and 7 of the strip line 5.
