Definitions
- the invention relates to a high-frequency filter in coaxial design according to the preamble of claim 1.
- a common antenna is frequently used for transmit and receive signals.
- the transmit or receive signals each use different frequency ranges, and the antenna must be capable of 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 reception signals are forwarded from the antenna to the receiver.
- high-frequency filters are used in coaxial design.
- High frequency filters in coaxial design include coaxial Resonators in which resonator cavities are formed in an outer conductor housing, in which inner conductors are arranged in the form of inner conductor tubes or cylinders.
- the inner conductor tubes each have a free end which lies adjacent to a lid which is arranged on the upper side of the housing.
- the inner conductor or parts of the inner conductor are made of a different material than the housing, an impurity always occurs between two materials, even if both are soldered together. This can cause intermodulation problems apart from manufacturing issues. Furthermore, several different materials must be joined together in the high-frequency-critical resonator chamber, wherein mechanical tolerances in this room can have serious effects on the filter. If an inner conductor z. B. not placed within a few hundredths of a millimeter in the filter, the coupling bandwidth changes to all adjacent resonators, which in turn can bring problems in the vote with it.
- This high-frequency filter having a temperature compensation device comprises an outer conductor housing with an axially arranged thereon
- the inner conductor tube ends at a distance below a lid closing the outer conductor housing.
- the inner conductor tube is provided with an inner Provided terrohr passing through the longitudinal bore, in which from below a screw can be screwed.
- the screw can be screwed into a counterpart, which has a circumferential edge at a distance from the free end of the inner conductor tube, so that a bellows-shaped element can be inserted between this peripheral edge of the counterpart and the free end edge of the inner conductor tube.
- the screw has a coefficient of thermal expansion which is less than the thermal expansion coefficient of the existing example of aluminum inner conductor tube.
- the bellows-shaped compensation element further consists of a different material compared to the material of the screw and the inner conductor tube.
- this embodiment also has various disadvantages, since additional elements are necessary, the bellows-shaped element has to be welded to the circumferential end wall of the inner conductor tube, etc. Intermodulation problems may also be caused thereby.
- a pot circuit or a loaded cavity resonator with a temperature compensation has also become known from DE 41 13 302 C2. It is also a high frequency filter in coaxial design with an outer conductor and an inner conductor. Adjacent to the free end the inner conductor is arranged a housing cover. Above the lid, a strip-shaped bracket is arranged, which is screwed to the upper peripheral edge of the cylindrical housing of the resonator. Between the lid facing the bottom of this bracket and the top cover a block is inserted. The bracket is dimensioned in its length and in this case has a coefficient of thermal expansion, that with an increase in temperature, the longitudinal extension of the bracket is greater or greater than the extension of the underlying cover. As a result, the lid, which is curved convexly inward into the interior of the resonator, is no longer deflected so much. This reduction in deflection reduces the capacitance between the inner conductor and the lid, causing compensation.
- a deviating compensation principle can be taken from US 2003/0193379 AI as known. It is also again a microwave filter in a coaxial construction with a screw screwed in the lid, which can engage different degrees in an axial inner recess of the inner conductor. As usual, this screw element serves to set the resonator frequency.
- this prior publication describes different compensation devices, which basically consist of a plate-shaped compensation disc, which is arranged for example on the inside of the lid. This disc is provided with a passage opening through which this helical adjusting element protrudes. This disc connected to the lid has a different coefficient of expansion, such that the bimetal effect ultimately causes the cover to deflect, whereby the distance between the end face of the inner conductor and the inner side of the cover or the disc-shaped compensation element provided there changes in the sense of temperature compensation.
- a compensation device has basically also become known from US Pat. No. 5,867,077. There is, however, a cavity filter without an inner resonator, so not a cavity filter in coaxial design with an inner conductor.
- the object of the invention is in contrast to provide a high-frequency filter in a coaxial design, which is easier to manufacture and cheaper to produce than known from the prior art filter. This object is achieved according to the features specified in claim 1 and in claim 2.
- the dependent claims describe advantageous embodiments of the high-frequency filter.
- the peculiarity of the solution according to the invention lies in the fact that the compensation device does not consist of additional attachable, mountable or otherwise provided parts in order to effect the desired compensation effect with a temperature change.
- the invention proposes that only the existing parts of the coaxial cavity filter, that is, the housing wall surrounding the cavity (at least in a partial height) and / or the resonator interior be adjacent cover (lid body) at least partially made of a corresponding material to realize the desired temperature compensation in the event of a change in temperature and thereby caused change in length of the material used without additional equipment.
- a correspondingly adapted wall section which, for example, represents a part of the housing wall of the resonator or a part of the lid of the resonator, ie those parts which also delimit the resonator interior. It is therefore not additional externally attached to the resonator or provided there additional measures to effect compensation, as proposed, for example, DE 41 13 302 C2.
- corresponding wall sections that extend in the axial direction of the resonator or at least with an axial component in the direction of the resonator and not perpendicular thereto, as proposed by using an additional plate according to US 2003/0193379 AI.
- the high-frequency filter according to the invention comprises a compensation device, which in turn comprises at least one wall section extending in the axial direction, which is connected to a housing wall of the outer conductor housing and / or integrated in a housing cover.
- the housing wall of the outer conductor housing is made of a first material having a first coefficient of thermal expansion
- the compensation device consists of a second material or comprises a second material having a second coefficient of thermal expansion which is greater than the first coefficient of thermal expansion of the first material.
- the axial direction is the axial direction with respect to the inner conductor and thus parallel to the longitudinal extent of the inner conductor. Since the second coefficient of thermal expansion of the second material is greater than the first coefficient of thermal expansion of the first material, and since the compensation device comprises an axially extending wall section of the second material, the distance of the at least one section of the housing cover changes more than a temperature change if the compensation device would not comprise a wall section of the second material extending in the axial direction. Therefore, the inner conductor, for example, made of the same material as the outer conductor housing and in particular the housing wall, so that the inner conductor in its axial length due to the increase in temperature less length than extending in the axial direction wall portion of the compensation device.
- the outer conductor housing can in particular be formed integrally with the inner conductor, so that the production costs are reduced. Also, no expensive materials have to be used for the inner conductor, which have a low coefficient of thermal expansion. Due to the possible one-piece of the Outer conductor housing and the inner conductor also accounts for intermodulation problems at any contact points of the inner conductor with the housing bottom.
- the high-frequency filter according to the invention thus achieves with relatively simple means an increase in the distance between the inner conductor tube and the cover at a temperature increase, so that the falling resonance frequency of the filter due to the mechanical elongation is compensated with increasing temperature, since the distance of the free end of the inner conductor to the at least a portion of the housing cover increases disproportionately.
- the compensation device comprises a compensating element, which comprises the wall section extending in the axial direction and is arranged between the housing wall and the housing cover.
- a corresponding compensation device can be realized very simply as part of the housing wall and can be arranged in any area of the housing wall.
- a correspondingly constructed high-frequency filter is therefore particularly simple and therefore particularly cost-effective.
- the compensation element is mechanically connected to the housing wall in the region of its free end and to the housing cover. Consequently, the compensation element between the free end of the housing wall and the housing cover is arranged.
- a corresponding compensation element can be produced particularly easily and is therefore particularly cost-effective.
- the compensation element can be arranged, for example, in the form of an intermediate layer or in the form of an intermediate ring between the housing cover and the housing wall.
- the inner conductor is designed as an inner conductor tube with a longitudinal recess.
- the housing cover preferably has a housing cover opening, and the compensation device comprises a compensation ring, which comprises the wall section extending in the axial direction.
- the compensation ring is connected to a side facing away from the inner conductor outside of the housing cover with this and forms with the housing cover opening a common passage.
- the resonator further comprises a pin, which is held by means of the compensation ring, wherein the pin protrudes through the common passage of the housing cover and the compensation ring in the longitudinal recess of the inner conductor tube.
- a corresponding embodiment of the high-frequency filter is particularly simple and inexpensive to produce, since the compensation element simply consists of a compensation ring.
- the pin is designed as AbStimmelement, the positionally variable in its axial position by the
- Compensation ring is held so that a depth of immersion of AbStimmides in the longitudinal recess of the mecaniclei- terrohres is variable.
- the compensation ring consists of metal or a metallically coated plastic.
- the compensation device comprises a protuberance directed away from the inner conductor in the housing cover, wherein the protuberance comprises the wall section extending in the axial direction.
- the compensation device is formed as an integral part of the housing cover and therefore particularly simple and inexpensive to manufacture.
- the length of the wall section extending in the axial direction increases with a temperature increase, whereas the length of the wall section extending in the axial direction decreases with a decrease in temperature.
- the distance of the free end of the inner conductor tube increases to at least a portion of the housing cover at a temperature increase, whereas the distance of the free end of the inner conductor to at least a portion of the housing cover decreases with a temperature decrease.
- the extending in the axial direction wall portion of the protuberance extends in plan view of the resonator at a distance from the housing wall and the inner conductor.
- the distance of the free end of the inner conductor to the at least one section of the housing cover changes both in the axial direction and in the radial direction with a temperature change.
- the wall section extending in the axial direction extends at least partially around the inner conductor in the direction of the housing bottom and in plan view of the resonator.
- the radial portion of the free end of the inner conductor changes to the at least a portion of the housing cover. Since the compensation device extends only inwardly toward the interior of the high-frequency filter, the filter may have a flat upper surface and moreover have a smaller size in the axial direction.
- the length of the wall section extending in the axial direction is preferably between 2% and 50%, more preferably between 5% and 35%, more preferably between 10% and 25% of the length of the housing wall extending in the axial direction. Also in the solution according to claim 6 also takes place a temperature compensation. With a temperature-induced expansion of the material of the lid, the walls projecting into the resonator interior (which completely or partially surround the inner conductor) propagate further outward in the radial direction, thereby increasing the distance between these walls and the inner conductor, thereby causing the temperature compensation.

- FIG. 1 shows a high-frequency filter known from the prior art.
- the high-frequency filter comprises at least one resonator 1, wherein the high-frequency filter can also comprise a plurality of resonators 1 coupled to one another.
- Each resonator 1 comprises an inner conductor 10 and an outer conductor housing.
- the outer conductor housing comprises a housing bottom 20, a housing cover 22 spaced from the housing bottom 20 and a housing wall 24 encircling the housing bottom 20 and the housing cover 22.
- FIG. 1 shows that the inner lining 10 with the housing bottom 20 and the housing wall 24 is formed in one piece.
- the housing cover 22 rests on the free ends of the housing wall 24 and is mechanically connected by means of screws 40 with the end faces of the housing wall 24.
- a free end 11 of the inner conductor 10, which is the end face of the inner conductor 10, has a predetermined distance to the inside of the housing cover 22.
- the housing wall 24 with the housing bottom 20 and with the Inner conductor 10 is integrally formed, the housing wall 24 and the inner conductor 10 made of the same material with the same thermal expansion coefficient. When the temperature increases, the housing wall 24 expands in proportion to its axial length. The same applies to the inner conductor 10, which also expands in proportion to its axial length. Since the axial length of the housing wall 24 is greater than the axial length of the inner conductor 10, increases with a temperature increase, the distance of the free end 11 of the inner conductor 10 to the inner wall of the housing cover 22, so that the so-called head capacity decreases, which an increase in the resonant frequency leads. Since the axial length of the inner conductor 10 increases, but at the same time decreases the Resonanzfre- frequency of the filter, since the mechanical length of the inner conductor 10 is inversely proportional to the frequency.
- the corresponding lowering of the resonance frequency due to the lengthening of the axial length of the inner conductor 10 is greater than the increase in the resonance frequency associated with the temperature increase due to the decrease in the head capacitance, so that at a temperature increase or a temperature decrease, the resonance frequency of the corresponding resonator shifts.
- Corresponding resonators however, have a complex construction since the resonators are connected to the outer conductor housing. must and sic arise at the corresponding connection points intermodulation problems.

- the compensation element 30 can be realized, for example, in the form of an intermediate plate or a support plate, that is, in the form of an intermediate layer or an uppermost layer. Since the compensation element 30 extends in the axial direction, this comprises an axially extending wall portion 31. With a temperature increase, the compensation element 30 expands in proportion to its axial length more than the housing wall 24 and the inner conductor 10, so that the distance between the free end 11, ie the front end IIa of the inner conductor 10 to the inside of the housing cover 22 disproportionately increased.
- the head capacitance of the corresponding resonator 1 decreases, so that the resonance frequency of the resonator 1 increases.
- the compensation element 30 in its axial thickness and by suitable choice of the material can at a temperature change, the concomitant change in the resonant frequency just be designed so that this change in the resonant frequency of the change in the resonant frequency due to the change in length of the inner conductor and thus compensates for this.
- the thus constructed high-frequency filter thus has a temperature compensation and frequency stabilization.
- the compensation device does not consist of a separate part attached anywhere or includes this, but that the compensation device according to the invention consists of a housing interior, that is, the resonator 50 interior limiting wall portion.
- this wall section shown in Figure 2 could also be formed at any other location, for example, the bottom 20 closer lying in any central region of the housing wall 24 or even in an immediately adjacent to the housing bottom 20 area.
- a temperature increase causes the axial height of the coaxial resonator increases, whereby the corresponding distance between the lid inner side and the end face IIa of the inner conductor increases to effect the temperature compensation.

- the high-frequency filter according to the tenth embodiment differs from the high-frequency filter of the ninth embodiment in that the pin 25 is formed as a tuning element 25 which is held in its axial position variable in Kompensationsring 34, so that the immersion depth of the tuning element 25 in the longitudinal recess 12th of the inner conductor tube 10 is variable.
- the head region of the tuning element 25 can have an external thread
- the compensation ring 34 has an internal thread, so that the immersion depth of the tuning element 25 into the longitudinal recess 12 can be changed by turning the tuning element 25.
- the compensation ring 34 may for example be formed of a plastic, the outside of which is metallized. Alternatively, the compensation ring 34 may be formed of a metallic material having a desired coefficient of expansion.
- FIG. 12 shows, in a schematic side sectional view, a high-frequency filter according to an eleventh embodiment of the present invention.
- the high frequency filter according to the eleventh embodiment is a modification of the high frequency filter according to the fourth embodiment.
- the housing cover 22 has a circumferential groove around the inner conductor 10, which compensates for mechanical deformations of the housing cover due to temperature changes.
- the outside of the housing cover thus has a circumferential groove.
- FIG. 13 shows, in a schematic side sectional view, a high-frequency filter according to a twelfth embodiment of the present invention.
- the illustrated high-frequency filter is characterized in that the inner conductor 10 is formed as an inner conductor tube 10 with a longitudinal recess 12.
- the housing cover 22 includes a pin 25 connected thereto, which projects into the longitudinal recess 12 of the inner conductor tube. Furthermore, the housing cover 22 has the wall section 31 extending in the axial direction, so that when the temperature changes, the penetration depth of the pin 25 into the longitudinal recess 12 of the inner conductor tube 10 is variable.
- the outer conductor housing may be formed of, for example, aluminum, brass, invar steel, cast aluminum or metallized plastic.
- the housing cover 22 may be formed, for example, of aluminum or of metallised acrylonitrile-butadiene-styrene (ABS plastic).
- ABS plastic metallised acrylonitrile-butadiene-styrene
- the inner conductor can be made of the same materials as the outer conductor housing and can also be made of iron, steel or brass.
