Definitions

  • the invention relates to a high-frequency conductor system with a line-bound HF bushing, in particular in the form of an HF filter.
  • a high-frequency conductor system is used, for example, in radio-technical systems, in particular in the mobile radio sector.
  • a common antenna is often used for the 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 therefore required, with which on the one hand the transmitted signals from the transmitter to the antenna and on the other hand the received signals from the antenna to the receiver are passed on.
  • high-frequency filters in cavity design and / or coaxial design are used to split the transmitted and received signals.
  • a pair of high-frequency filters can be used, both of which allow a specific frequency band to pass through (band-pass filter).
  • a pair of high-frequency filters can be used, both of which block a specific frequency band (band-stop filter).
  • a pair of high-frequency filters can be used, one of which allows frequencies below a frequency between the transmission and reception band to pass and blocks frequencies above this frequency (low-pass filter) and the other filter frequencies below a frequency between the transmission and reception band and allows higher frequencies to pass through (High pass filter).
  • Other combinations of the filter types just mentioned are also conceivable.
  • Such filters often have a coaxial structure, since they consist of milled or cast parts, making them easy to manufacture.
  • a high-frequency filter which has a conductor track which is spaced apart on a metal layer.
  • the conductor track comprises sections with a widened diameter (stub line) which extend outwardly perpendicular to the course of the conductor track in one or both sides.
  • a housing with a housing wall and a housing cover covers the conductor track and is adapted in terms of geometry to the course of the conductor track.
  • the WO 2009/082117 A1 shows a high-frequency filter in stripline technology, the inner conductor having several stub lines.
  • the shape of the housing follows the course of the inner conductor with its streak lines.
  • a high-frequency filter which has an outer conductor and an inner conductor.
  • the inner conductor consists of several inner conductor sections which are capacitively coupled to one another with the formation of a distance between them.
  • the inner conductor consists of plate-like elements that are connected to one another via a connecting piece.
  • the plate-like elements are formed in one piece together with the connecting piece.
  • a partition which is part of the housing, is arranged between two plate-like elements, so that no direct coupling is possible.
  • This partition wall comprises an opening through which the respective connecting piece extends.
  • the plate-like elements have end faces which point in the direction of the respective partition wall.
  • the plate-like elements also include larger side surfaces that point towards the housing and through which there is a capacitive coupling to the housing.
  • the DE 12 64 636 B describes a high-frequency filter which comprises a cylindrical tube in which an inner conductor is arranged, the cylindrical tube having an abrupt expansion of its outer conductor sections. In the area of this sudden expansion, the inner conductor is expanded in the form of a circular metallic disc.
  • the GB 1 046 277 A shows a high-frequency filter which comprises a filter housing in which an inner conductor runs. Partition walls divide the receiving space in the filter housing into individual chambers, the partition walls having an opening through which the inner conductor is passed. The partition walls are attached at their ends to an RF absorbing material.
  • the inner conductor comprises segments with a larger diameter, this diameter nevertheless being smaller than the opening in the respective partition walls, so that the inner conductor can be pushed through the partition walls.
  • the KR 100 928 915 B1 also describes an HF filter in a cavity design.
  • a housing base and circumferential housing walls are provided which surround a receiving space which is closed by a cover arrangement.
  • This receiving space is divided into a large number of resonator chambers by dividers.
  • These separators comprise an opening through which an inner conductor with a constant inner conductor cross-section can be passed.
  • a high-frequency conductor system with several chambers is known, which can be used, for example, to filter RF signals.
  • the high-frequency conductor system 1 is shown in plan view with the lid open. This comprises a high-frequency housing 2, an RF bushing 3 in the form of an inner conductor and a connector 4 in the form of a coaxial plug.
  • the HF bushing 3 is guided through cross connections 5, which subdivide and support the high-frequency conductor system 1 into various chambers 6 1 to 6 n. These cross connections 5 have a receiving opening in the axial direction.
  • the high-frequency housing 2 is preferably milled out of a workpiece, the cross connections 5 being left in place.
  • a part of the HF bushing 3 has areas 19 which are used for capacitive coupling with the high-frequency housing 2. These areas 19 are formed by widening the RF feedthrough 3. These areas 19 have a round cross-section in plan view parallel to the course of the HF feedthrough. The capacitive coupling takes place on the side circumferential surface of these areas 19 towards the high-frequency housing 2.
  • a disadvantage of the prior art Figure 9 is that the capacitive coupling is not exactly reproducible.
  • the high-frequency conductor system comprises a high-frequency housing which comprises a housing base, a housing cover spaced apart from the housing base and a housing wall running around between the housing base and the housing cover, whereby a receiving space is formed.
  • the circumferential housing wall has a first housing wall and a second housing wall, the second housing wall being opposite the first housing wall.
  • at least one line-bound HF bushing is arranged within the receiving space. This is galvanically separated from the high-frequency housing.
  • At least one capacitive coupling element is arranged on at least part of the circumference of the line-bound HF bushing and is galvanically connected to the wire-bound HF bushing.
  • Each capacitive coupling element has two opposite end faces, which are aligned transversely or perpendicularly to the direction of propagation of the line-based RF feedthrough.
  • At least one first coupling web is galvanically connected to the high-frequency housing and protrudes at least partially into the receiving space.
  • the at least one first coupling web is arranged at a distance from at least a first part of at least one of the two end faces of the capacitive coupling element for generating a capacitive coupling. For example, more than 50%, or more than 60%, 70%, 80%, 90%, or more than 95% of the total capacitive coupling between the capacitive coupling element and the high-frequency housing takes place via one or both end faces and the at least one coupling web.
  • At least one second coupling web is provided, the at least one second coupling web is arranged at a distance from the respective first coupling web in the direction of propagation of the line-bound HF bushing, and a first coupling chamber is formed between the two coupling webs.
  • at least one third and at least one fourth coupling web are provided, which protrude into the receiving space and are arranged on a housing wall opposite the housing wall on which the first coupling chamber with the first and second coupling web are arranged.
  • At least a first part of the at least one capacitive coupling element protrudes into the respective first coupling chamber between the respective first and the respective second coupling web, the first coupling web towards one of the two opposite end faces and the second coupling web towards the opposite end face of the respective capacitive coupling element for generating a capacitive coupling between the wired HF bushing and the high-frequency housing are arranged on the two end faces.
  • At least a second part of the at least one capacitive coupling element protrudes into the respective second coupling chamber between the respective third and the respective fourth coupling web.
  • the third coupling web is in each case to one of the two opposite end faces and the fourth coupling web is arranged in each case on the opposite end face of the respective capacitive coupling element to generate a capacitive coupling between the wired RF feedthrough and the high-frequency housing via the two end faces.
  • the third and fourth coupling webs are arranged on the housing base or the housing cover.
  • the coupling takes place via the end faces because they are flat, or each end face lies completely in one plane and is not spherically curved. Such an end face can be reproduced much more precisely than if it were designed to be cylindrical like the side circumferential surface. At the same time, the entire line-bound HF bushing can still be produced in one turning process.
  • the high-frequency conductor system also has at least one connection piece, in particular in the form of a coaxial plug, which enables electrical contact to be made with the line-bound HF bushing from outside the high-frequency housing.
  • a connection piece in particular in the form of a coaxial plug
  • the line-bound HF bushing is preferably supported solely by the at least one connection piece and is held in position within the receiving space at a distance from the high-frequency housing. As a result, further holding devices can be dispensed with, which means that production can be kept simple.
  • the high-frequency conductor system can provide at least one holding and positioning web, which at least partially protrudes into the receiving space and is completely penetrated by a receiving opening in its entire thickness in the direction of propagation, i.e. in the direction of extension of the line-based RF bushing .
  • the receiving opening is also accessible over the entire thickness of the holding and positioning web at least in a lateral direction transverse to the direction of propagation.
  • the holding and positioning web is therefore open transversely to the direction of propagation from the outside over its entire thickness towards the receiving opening.
  • the line-bound HF bushing is mounted inside the receiving opening on the at least one holding and positioning web.
  • the wired HF bushing can be inserted very easily into the high-frequency housing of the high-frequency conductor system. This in particular facilitates the introduction of the line-bound HF bushing into a high-frequency conductor system in which the wire-bound HF bushing should also have curves or kinks.
  • an insulating medium is preferably arranged between the line-bound HF feedthrough and the at least one holding and positioning web, whereby the holding and positioning web and the wired HF feedthrough are galvanically separated from one another.
  • the insulation medium is preferably an insulation sleeve which at least partially surrounds the line-bound HF bushing radially in the area where the wire-bound HF bushing is mounted on the holding and positioning web or this touched.
  • the insulating sleeve preferably has a receiving slot over its entire length, into which the line-bound HF bushing is inserted. This receiving slot is preferably also accessible across the length over the entire length. This allows the insulation sleeve to be connected very easily to the wired HF bushing. The insulation sleeve can therefore be attached to the side of the wired HF bushing.
  • the insulation sleeve has at least one coding projection and / or at least one coding opening on at least part of its circumference, which engages in at least one coding opening and / or at least one coding projection on the holding and positioning web. This creates a precise fit of the insulation sleeve on the holding and positioning web, which also improves the mounting of the line-bound HF feedthrough on the holding and positioning web and thus within the receiving space.
  • a positioning element protruding beyond the cross section of the wired HF bushing is also preferably arranged on the wired HF bushing, whereby the insulating sleeve rests on the positioning element immovably or only to a limited extent in the direction of propagation of the HF bushing.
  • two positioning elements protruding beyond the cross-section of the line-bound HF bushing can also be arranged on the latter, in which case the insulating sleeve between these two positioning elements cannot be displaced or can only be displaced to a limited extent in the direction of propagation is arranged.
  • the at least one or both positioning elements act as a limit stop, which means that the insulation sleeve, which rests on the circumference of the HF bushing or through which the HF bushing runs, does not move in the direction of propagation, i.e. in the direction of extent of the HF bushing. Implementation on this can be postponed.
  • the positioning element extends in the direction of propagation preferably only over part of the length of the HF bushing and preferably has a shorter length than the insulating sleeve, which also extends only over part of the length of the HF bushing.
  • the positioning element is preferably designed in one piece with the wired HF bushing and is part of this.
  • the at least one positioning element can on the one hand have the shape of a positioning nose and therefore only extend over part of the circumference of the wired RF feedthrough in the direction of the high-frequency housing, or on the other hand it can preferably evenly extend over the entire circumference outwards, i.e. in the direction of the High frequency housing, extend.
  • the positioning element can be a melted and re-solidified solder, by means of which a limit stop acting for the insulating sleeve is created at a certain point of the HF feedthrough.
  • a third coupling web is arranged on the longitudinal wall of the receiving space opposite the first coupling web.
  • the fourth coupling web is arranged on the longitudinal wall of the receiving space opposite the second coupling web.
  • a coupling chamber in this case a second coupling chamber, is also formed between the third and fourth coupling webs. At least a second part of the capacitive coupling element protrudes into this second coupling chamber.
  • the at least one first coupling web overlies an end face of the capacitive coupling element on a larger area
  • an increase in the coupling capacitance is achieved than if the area were smaller.
  • This also applies in the event that the distance between the coupling web and the capacitive coupling element is reduced.
  • air is not used as the dielectric between the at least one first coupling web and the capacitive coupling element, but for example a potting compound.
  • the at least one first coupling web is in one piece with the housing base and / or the housing wall formed and part of this.
  • one of these coupling webs can be attached to the housing cover, in which case the attachment is preferably implemented by means of a screw connection.
  • the housing base and / or the housing wall has at least one recess.
  • the at least one recess is formed in the area of a peripheral side surface of the at least one capacitive coupling element, which reduces capacitive coupling between the peripheral side surface of the at least one capacitive coupling element and the high-frequency housing.
  • This is particularly due to the fact that the capacitive coupling element together with the RF feedthrough is preferably produced as a turned part, the tolerances for producing round bodies being much higher than for producing flat surfaces.
  • These recesses therefore ensure that the capacitive coupling takes place predominantly only via those that are mechanically more precisely reproducible, such as, for example, the flat end faces.
  • the high-frequency housing may have at least one opening through which a tuning element can be inserted or introduced.
  • the at least one tuning element is radial to a circumferential side surface of the at least one capacitive coupling element arranged.
  • the at least one tuning element can, however, also impinge on a side surface of the capacitive coupling element at a different angle and even touch it.
  • the at least one tuning element is preferably formed from a dielectric material, with the resonance frequencies of the high-frequency filter being able to be changed by introducing or screwing the tuning element into the receiving space of different widths.
  • the at least one tuning element can also be formed from a metal or at least partially provided with an electrically conductive coating.
  • the at least one capacitive coupling element and / or the at least one insulating sleeve and / or the at least one positioning element are connected centrally or eccentrically to the line-bound HF bushing.
  • the cross-sectional shape of the at least one insulating sleeve and / or the at least one capacitive coupling element and / or the at least one positioning element can also be selected differently and, in plan view, correspond, for example, to a square or a rectangle or an oval or a circle or a regular or irregular n-polygon or be approximated to it.
  • the receiving opening within the holding and positioning web widens, preferably conically in the direction transverse to the direction of propagation over the entire thickness in the direction of the high-frequency housing. If the receiving opening is open, for example, in the direction of the housing cover, the line-bound opening can be opened when the housing cover is removed HF feedthrough can be inserted very easily into the holding and positioning bar.
  • the holding and positioning web is preferably formed in one piece on the housing wall and / or on the housing base. It would also be possible that the holding and positioning web is formed on the housing cover or is screwed to the housing cover. In this case, the wired HF bushing is inserted into the holding and positioning bar before both are inserted into the open high-frequency housing. It should be noted that it is advantageous if the holding and positioning web protrudes so far into the receiving space that the wired HF bushing is centered in the receiving space, i.e. the minimum distance to the electrically conductive high-frequency housing is approximately the same.
  • FIG. 1 shows a three-dimensional representation of the high-frequency conductor system 1 according to the invention with the housing cover 70 open, as shown in FIG Fig. 7 is shown.
  • the high-frequency conductor system 1 has a high-frequency housing 2, which comprises a housing base 7, a housing cover spaced apart from the housing base 7 and a housing wall 8, 9 running around between the housing base 7 and the housing cover 70, whereby a receiving space 10 is formed.
  • a wired HF bushing 3 is arranged within the receiving space 10 of the high-frequency housing 2.
  • the wired HF bushing 3 is galvanically separated from the high-frequency housing 2.
  • the RF feedthrough 3 is passed through openings in the cross connections 5 and stored in these galvanically separated, these openings being created by a drill or milling cutter introduced into the connection piece 4, the drill having slight play or swinging at the tip , which leads to the fact that the cross connections 5, which are most distant from the receiving opening, are no longer pierced cleanly and centered. Electroplating also takes place unevenly and the layer thickness cannot be set exactly. Deburring to reduce surface roughness is also difficult. As a result, the filter behavior deteriorates and a sufficiently high reproducibility with regard to the electrical properties is no longer given during manufacture. This means that, due to the different mounting of the HF bushing 3, the distance between the areas 19 and the high-frequency housing 2 is different, whereby the capacitive Coupling turns out differently and thus the filter behavior changes.
  • the high-frequency conductor system 1 also has at least one holding and positioning web 11, which protrudes at least partially into the receiving space 10 and which completely extends over its entire thickness, i.e. across its entire width in the direction of propagation 12 of the line-bound RF feedthrough 3, from a receiving opening 13 is interspersed.
  • the receiving opening 13 through which the RF feedthrough 3 runs is also accessible at least in one lateral direction transverse to the direction of propagation 12 over the entire thickness, that is to say over the entire width of the holding and positioning web 11.
  • the line-bound RF feedthrough 3 is mounted within the receiving opening 13 on the at least one holding and positioning web 11.
  • the wired HF bushing 3 can be inserted from above in the direction of the housing bottom 7 with the housing cover 70 open, being kept at a distance from the housing bottom 7 and from both housing walls 8, 9 by the holding and positioning web 11.
  • the holding and positioning web 11 is preferably formed in one piece on the housing wall 8, 9 and / or on the housing base 7.
  • the holding and positioning web 11 can, however, also consist of a separate element, which can preferably be fastened to the housing wall 8, 9 and / or to the housing base 7 or even to the housing cover 70 by means of a screw connection.
  • the holding and positioning web 11 can for example consist of plastic or have a core made of plastic, which is coated with a preferably electrically conductive medium.
  • the holding and positioning web 11 protrudes so far into the receiving space 10 that the line-bound RF feedthrough 3 is arranged centered within the receiving space 10. This means that it has approximately the same minimum distance from the housing walls 8, 9, the housing base 7 and the housing cover 70. The distance to the housing walls 8, 9, the housing base 7 and the housing cover 70 can, however, be freely determined and different depending on the application.
  • An insulation medium 14 is preferably also arranged between the line-bound HF feedthrough 3 and the at least one holding and positioning web 11, whereby the holding and positioning web 11 and the wired HF bushing 3 are galvanically separated from one another.
  • the holding and positioning web 11 consists of a dielectric, a separate insulation medium 14 can be dispensed with.
