Definitions

  • the invention relates to a coaxial resonator with the in Preamble of claim 1 specified characteristics.
  • the vote by means of a dielectric has the disadvantage a very narrow tuning range.
  • a tuning screw or a voting pen have the disadvantage that when voting Metal abrasion can arise, the intermodulation products can cause.
  • the invention is based on the object, a coaxial Resonator specified in the preamble of claim 1 To create a genre without the risk of the emergence of Intermodulation products over as large a range as possible is tunable.
  • the inside of the inner conductor tube and the metallic tuning body a coaxial lead.
  • the length of the inner conductor tube is dimensioned so that they are in the desired resonant frequency is equal to ⁇ / 4.
  • the front end of the inner conductor tube therefore acts as a short circuit, so that at this point a HF moderately ideal, but non-contact Contact between the inner conductor tube and the tuning body consists.
  • the rod of dielectric Material over which the tuning body moved will remain as well as the means for moving the rod however, without any influence on the resonance frequency, because that Pipe acts as a partially filled with dielectric Circular waveguide whose critical frequency due to the in Ratio to the wavelength of the resonant frequency low Diameter far above the resonant frequency, so that the adjusting mechanism in frequency from the AbstimmSystem completely decoupled.
  • the means of displacement The rod are basically arbitrary. For example, can the rod out of the tube and out of the housing and be displaceable from the outside. In this case, one is Guide bush or other guide means between the Rod and the inner wall of the pipe necessary to ensure that the tuning body is exactly coaxial with constant Width of the preferably small annular gap to the inner wall of the tube is slidable in this.
  • the tuning body is advantageous as the end of the rod surrounding pot formed (claim 4).
  • the pot can over part of its depth or over its entire depth be pressed or glued on the end of the rod.
  • the rod may be made of ceramic (claim 7), which the Advantage has, among ceramics with different thermal expansion coefficients to be able to choose. Because the rod but she is not in the field-filled room also be made of plastic.
  • the tuning body and the rod are made Materials with temperature coefficients so chosen are that the temperature-dependent change of the distance the end face of the tuning body from the inner surface of the Wall of the housing whose temperature-dependent dimensional changes compensated (claim 8). This can be the requirement for stability of the tuning or resonant frequency even over a very wide range of ambient temperatures be fulfilled.
  • the embodiment relates to a resonator, a center or resonant frequency of 1750 MHz and has a tuning range of 640 MHz.
  • the resonator is Part of a four-circuit band filter for mobile.
  • the resonator consists of a pot-shaped metal housing 1, in this embodiment both in side view as well as in the supervision is square. Other However, geometries are just as possible.
  • the housing 1 is closed by a lid 1a RF-tight. From the middle of the housing bottom 1b, a pipe 2 extends in the direction the lid 1a.
  • the tube 2 can, as shown, in one piece be with the ground 1b.
  • From the bottom side Opening is in the tube 2 a threaded bushing 3, for. pressed or glued.
  • the threaded bushing 3 has a Internal thread into which a tuning screw 4 is screwed.
  • the tuning screw 4 takes the lower end of a ceramic rod 5 on.
  • the length of the tube 2 is ⁇ / 4 of the center frequency of the resonator. Therefore arises at the free end of the tube 2, at the point S, between the AbstimmMech 6 and the tube 2 an HF-moderate Short circuit.
