Definitions

  • the invention relates to a high-frequency filter in a coaxial design, which can be tuned via at least one tuning element, wherein the tuning element is threadless within the high-frequency filter movable.
  • a common antenna is often used for transmit and receive signals.
  • the transmit and receive signals each use different frequency ranges, and the antenna must be suitable for transmitting and receiving in both frequency ranges.
  • a suitable frequency filtering is required, with the one hand, the transmission signals from the transmitter to the antenna and on the other hand, the received signals are forwarded from the antenna to the receiver.
  • high-frequency filters are used in coaxial design. Two interconnected high-frequency filters form a so-called duplex switch, which allows a largely decoupled interconnection of transmitters and receivers to a common antenna.
  • a pair of high-frequency filters can be used, both of which allow a certain frequency band (bandpass filter).
  • a pair of high frequency filters may be used, both of which block a particular frequency band (bandstop filter).
  • a pair of high frequency filters may be used, one of which filters below a frequency between transmit and receive bands and blocks frequencies above that frequency (low pass filter), and the other filter locks frequencies below a frequency between transmit and receive bands and above passing frequencies (high pass filter).
  • Other combinations of the just mentioned filter types are conceivable. This also applies to high-frequency filters, which are constructed as a single filter, ie have only one input and one output.
  • High-frequency filters which consist of coaxial resonators, can be easily produced from milling or casting parts.
  • these resonators ensure a high electrical quality and a relatively high temperature stability.
  • the US 2011/102110 A1 describes a high-frequency filter comprising a housing bottom, a housing cover spaced from the housing cover and a circumferential between the housing bottom and the housing cover housing wall.
  • a resonator inner conductor is galvanically connected to the housing bottom and extends in the direction of the housing cover.
  • the housing cover comprises an insertion opening above the resonator inner conductor.
  • this passage is penetrated by a tuning element.
  • the tuning element extends in the direction of the resonator inner conductor. Between the implementation and the tuning element, a sealing ring is still used.
  • the US 2011/0115575 A1 describes a high-frequency filter in cavity construction, which comprises a housing bottom, a housing cover spaced from the housing cover and a circumferential housing wall between the housing cover and the housing wall.
  • a first resonator inner conductor is attached to the housing bottom and extends in the direction of the housing cover.
  • a second resonator inner conductor is formed and extends in the direction of the first resonator inner conductor.
  • a helical tuning element can be screwed into an opening in the second resonator inner conductor, protruding therefrom within the high-frequency filter and extending in the direction of the first resonator inner conductor.
  • the double lines thus have the form of a Pipe part with the outer shell and a two-part inner conductor, wherein between the two parts a distance space is formed.
  • parts of the inner conductor are hollow, with a piston-like displaceable part is arranged in these. Between the two parts of the inner conductor and the piston-like displaceable part, an insulating piece is still arranged.
  • a high frequency filter in which tuning elements are introduced into the resonator.
  • the introduction of these tuning elements causes a change in the resonant frequency of the high-frequency filter.
  • the tuning elements are screwed in from outside the high-frequency filter. This is done via a threaded connection between the tuning element and a socket which is inserted into an opening of the high-frequency filter.
  • a disadvantage of the WO 2014/063829 A1 is that the introduction of such a socket is expensive together with the necessary thread and a vote can be difficult to automate.
  • An inner conductor is galvanically connected to an end face of the high-frequency housing and extends from this end face in the direction of an opposite further end face of the high-frequency housing. At this further end face a pin is arranged, which stretches in the direction of the inner conductor.
  • the inner conductor comprises an inner conductor bore into which the pin protrudes.
  • the inner conductor is formed in two parts, the second part being telescopic is longitudinally movable in the first part, whereby the inner conductor is constructed in several parts and variable in length.
  • the distance by which the second part of the inner conductor relative to the first part of the inner conductor can be moved can be adjusted by a threaded rod, which is fixedly connected to the second part of the inner conductor and is actuated from the outside of the high-frequency filter.
  • Another high-frequency filter is known.
  • This comprises an inner conductor, which is galvanically connected to a housing bottom of the high-frequency filter and extends from the housing bottom in the direction of the housing cover.
  • a first tuning element extends from the housing cover in the direction of the housing bottom.
  • the inner conductor includes an inner conductor bore into which the first tuning element extends.
  • a second tuning element can be screwed or inserted from outside the high-frequency filter in the inner conductor bore via a thread.
  • a disadvantage of the DE 10 2010 056 048 A1 is that when using a thread can cause abrasion, which leads to intermodulation products.
  • the diameter of the inner conductor bore and the outer diameter of the Abstimmelements must be very closely matched, so that a permanent grip is ensured.
  • the object of the present invention is therefore a high-frequency filter and a method for tuning of the high-frequency filter, which compared to the prior art cheaper and easier to manufacture, and is carried out and delivers better results over a longer period.
  • the object is achieved with respect to the high-frequency filter by the features of claim 1 and with respect to the method for adjusting the high-frequency filter by the features of claim 14.
  • the high-frequency filter according to the invention in coaxial design comprises at least one resonator with a first inner conductor and with an outer conductor housing.
  • the outer conductor housing comprises a housing bottom, a housing cover which is at a distance from the housing bottom, and a housing wall which rotates between the housing bottom and the housing cover.
  • a first inner conductor is galvanically connected to the housing bottom and extends in the axial direction from the housing bottom in the direction of the housing cover.
  • the first inner conductor ends at a distance in front of the housing cover and / or is galvanically separated from the housing cover.
  • the resonator further comprises a second inner conductor, which is galvanically connected to the housing cover and extending in the axial direction from the housing cover in the direction of the housing bottom.
  • the first and the second inner conductor are axially non-displaceable, so length variably arranged and coaxial with each other.
  • the first inner conductor and the housing bottom, as well as the second inner conductor and the housing cover preferably formed in one piece.
  • the first and / or second inner conductor have an inner conductor bore.
  • the inner conductor bore of the first or second inner conductor passes through the outer conductor housing and opens into an insertion opening.
  • a tuning element is arranged axially displaceable within the inner conductor bore of the first or second inner conductor.
  • the tuning element is designed and / or arranged so that a portion of the Abstimmelements dips to different depths in the free space between the two inner conductors.
  • a bush or a sleeve within the inner conductor bore between the first inner conductor and the tuning element or the second inner conductor and the tuning element is arranged positively or non-positively.
  • the tuning element has a region with a widened diameter, this region being located either in the center of the tuning element and / or at the end of the tuning element, which is arranged closer to the insertion opening.
  • the region with the widened diameter is elastically deformable, at least in the radial direction, on the longitudinal axis, which extends centrally through the tuning element.
  • the tuning element is preferably permanently fixed within the inner conductor bore. This is done by means of an adhesive bond, wherein the adhesive bond is introduced from outside the outer conductor housing via the insertion opening in the inner conductor bore, whereby the end of the Abstimmelements, which is closer to the insertion, is connected to the inner wall of the inner conductor bore.
  • the tuning element is axially displaceable, whereby no thread is necessary. Due to the fact that the tuning element is axially displaceable in the inner conductor bore, smaller filters can be produced because the diameter of the inner conductor bore is no longer limited to a minimum diameter which was previously necessary in order to be able to receive a thread. The elimination of the thread also results in less metallic abrasion during tuning, which would cause disturbing effects in the high-frequency filter (PIM - passive intermodulation).
  • the tuning element can for example be pressed in, preferably injected with compressed air into the inner conductor bore. It is furthermore advantageous that, in addition to a first inner conductor, there is also a second inner conductor, wherein both inner conductors extend coaxially toward one another.

  • the inner conductor bore does not need to be specially aftertreated to ensure that the tuning element fits snugly.
  • the inner conductor bore can be made with a uniform diameter. Later, then by choosing the appropriate socket or sleeve, the diameter of the tuning element can be chosen arbitrarily. Characterized in that the tuning element has an elastic region with a widened diameter, it can be ensured even without the use of a thread that the tuning element sits securely and permanently within the inner conductor bore.
  • the threadless shifting is not known in this context. True, in the US 4,460,878 shown a threadless displacement of various components, but this is not a tuning element, but an extension of the inner conductor.
  • the use of multiple inner conductors, as well as their non-displaceable attachment to a housing cover and on a housing bottom is shown just as little as that the inner conductor bore of the first or second inner conductor opens into an insertion opening on the outer conductor housing and thus is directly accessible from the outside. Furthermore, no use of a socket or sleeve is taught. Nor is it shown that the tuning element should have a widened region that is elastic.
  • the inventive method for tuning the high-frequency filter comprises various process steps.
  • a first method step the high frequency filter is closed.
  • a connection is made between a fastening device which is arranged on the tuning element, with a coupling device of the adjusting device.

  • the axial displacement of the tuning element within the inner conductor bore which can be done particularly easily via the coupling device, which is part of the adjusting device, by means of a linear motor or stepper motor.

  • the region with the enlarged diameter can be made at least partially slotted.
