Definitions
- the invention relates to a device for connecting a coaxial line to a coplanar line for the transmission of high bit rate data signals, in which the coaxial line has a coaxial inner conductor and a first dielectric layer enclosing the coaxial inner conductor, which in turn is enclosed by a coaxial outer conductor.
- the coplanar line has a second dielectric layer, on the front of which a coplanar inner conductor and a first and second coplanar outer conductor are applied, and the back of which has a metallization layer followed by a substrate carrier layer.
- the first and second coplanar outer conductors are separated from the coplanar inner conductor via the second dielectric layer and the coaxial inner conductor is connected to the coplanar inner conductor and the coaxial outer conductor is connected to the first and second coplanar outer conductors.
- the coaxial connector 1 has a coaxial inner conductor 2, a first dielectric layer 3 and a coaxial outer conductor 4.
- the coplanar line 5 consists of a line layer (6, 7, 8) followed by a second dielectric layer 9, a metallization layer 10 and a substrate carrier layer 11.
- the line layer (6, 7, 8) consists of a coplanar inner conductor 6 and a first and second coplanar outer conductor 6, 7, which are separated from the coplanar inner conductor 6 via the second dielectric layer 9.
- the coaxial inner conductor 2 of the coaxial connector 1 is with the inner coplanar conductor 6
- the second dielectric layer 9 of the coplanar line 5 is usually attached via the metallization layer 10 to a metallic substrate support layer 11, which serves both as mechanical stabilization and for heat dissipation and heat distribution of components provided on the second dielectric layer 9.
- the dispersion in the waveguide is to be kept as low as possible. This is achieved by closely coupling the first and second outer coplanar conductors 7, 8 to the inner coplanar conductor 6: small width of the inner coplanar conductor 6, small distance between inner coplanar conductor 6 and outer coplanar conductors 7, 8 and small thickness of the second dielectric layer 9.
- the geometry of the coaxial plug 1 requires a minimum width in the circumference of the coplanar inner conductor 6 at the connection point of the coaxial inner conductor 2 with the coplanar inner conductor 6. This is made possible by a continuous broadening of the coplanar inner conductor 6 and the distances between the coplanar inner conductor 6 and the first and second coplanar outer conductors 7, 8 reached near the contact point.
- a possible form of realization of the described geometry is shown as an example in FIG. 2.
- a device for connecting a coaxial connector to a coplanar line is known from US Pat. No. 5,404,117, in which the capacitive load is compensated by an inductive component.
- This is formed by a floating arrangement of the coaxial inner conductor and by a special shape of the coaxial outer conductor or a possibly existing dielectric at the transition point.
- These designs are adapted to the substrate material of the coplanar line, but require a relatively high mechanical outlay and cannot be used when using commercially available coaxial connectors (e.g. Anritsu V115FCPW).
- a "coaxial-to-coplanar waveguide transmission line" connector is known from US Pat. No. 5,570,068, in which a shaping of the electric field from coaxial in the direction within the coaxial line on coplanar through a separate milling of the coaxial outer conductor near the transition point.
- the shape of this milling is adapted to the substrate material used in the coplanar line.
- the mechanical outlay is relatively high, and the arrangement is difficult to use when using commercially available coaxial connectors.
- the object of the invention is to provide a device for connecting a coaxial line to a coplanar line, with the aid of which the capacitive line covering occurring at the connection point between the coaxial line and the coplanar line during the transmission of high bit rate data signals can be compensated with little technical effort.
- the problems are solved on the basis of a device according to the features of the preamble of claim 1 by its characterizing features.
- the metallization layer has a cutout which begins at the connection point between the coaxial connector and the coplanar line and runs almost symmetrically to the inner coplanar line and tapers in the direction of the inner coplanar line with increasing distance from the connection point.
- the capacitive line load is advantageously compensated for by a recess in the rear metallization of the coplanar line in the vicinity of the transition point to the coaxial line.
- the edges of the recess run almost symmetrically to the inner coplanar conductor in the implementation according to the invention and the recess tapers in the direction of the inner coplanar conductor with increasing distance from the connection point, ie edges of the recess running parallel to one another are thereby avoided.
- Particularly good resonance properties are achieved, for example, by using a triangular cutout.
- a cutout in the substrate support layer which is congruent with the recess in the metallization layer or larger is provided in the substrate support layer. This advantageously avoids a short circuit in the cutout.
- FIG. 1 shows a device for connecting a coaxial connector with a coplanar line according to the prior art
- FIG. 2 shows an example of a top view of the device according to the prior art shown in FIG. 1 in a schematic illustration
- FIG. 3 shows an example of a device for connecting a coaxial connector to a coplanar line using the cutout according to the invention
- FIG. 4 shows a section of the coplanar line, which describes the geometry of the recess according to the invention in the metallization layer in more detail;
- FIG. 5 shows a further exemplary embodiment of the device according to the invention using a side view of the device shown in FIG. 3 when using a metallic substrate support layer;
- FIG. 6 uses a first and a second diagram to show the reflection and transmission behavior at the transition point between the coaxial connector and the coplanar line.
- FIG. 3 shows an example of an embodiment of a device for connecting a coaxial line, in particular a coaxial connector 1 with a coplanar line 5 for the transmission of high bit rate data signals.
- the coaxial line is represented in FIG. 3 by way of example by the coaxial connector 1 and, analogously to the embodiment shown in FIG. 1, has a coaxial inner conductor 2, a first dielectric layer 3 and a coaxial outer conductor 4.
- the coplanar line 5 consists of a line layer (6, 7, 8) followed by a second dielectric layer 9, a metallization layer 10 and a substrate support layer 11.
- the line layer (6, 7, 8) consists of an inner coplanar conductor 6 and a first and second outer coplanar conductor 7, 8, the first and second coplanar outer conductors 7, 8 being separated from the coplanar inner conductor 6, for example via the second dielectric layer 9.
- the coaxial inner conductor 2 of the coaxial connector 1 is connected to the coplanar inner conductor 6 of the coplanar line 5 and the coaxial outer conductor 4 coaxial connector 1 to the first and second coplanar outer conductor 7, 8 of the coplanar line 5 and to the metallization layer 10 located on the rear side of the second dielectric layer 9.
- the metallization layer 10 and the first and second coplanar outer conductor 7, 8 can be grounded.
- the second dielectric layer 9 of the coplanar line 5 is applied analogously to FIG. 1 via the metallization layer 10 on a metallic substrate support layer 11.
- a recess 12 is provided in the metallization layer 10 according to the invention to compensate for the capacitive line coating which occurs when high-bit rate data signals are transmitted at the connection point between the coaxial line or coaxial connector 1 and the coplanar line 5.
- the recess runs almost symmetrically to the inner coplanar conductor and tapers in the direction of the inner coplanar conductor with increasing distance from the connection point.
- the thickness of the recess corresponds to the thickness of the metallization layer 10 or larger. In the exemplary embodiment shown, the recess is triangular, which means that a very good compensation effect can be achieved.
- the width of the cutout 12 at the connection point between the coaxial line or the coaxial extension 1 and the grounded coplanar line 5 corresponds almost to the diameter of the first dielectric layer 3, which circularly surrounds the coaxial inner conductor 2, for example. Furthermore, the length of the cutout 12 at the connection point between the Coaxial connector 1 and the grounded coplanar line 5 along the inner coplanar conductor 6 larger than the overlap area of the coaxial inner conductor 2 with the inner coplanar conductor 6.
- the underside of the metallization layer 10 is shown separately from the substrate support layer 11 as a surface drawn in broken lines.
- the course of the inner coplanar conductor 6 and of the first and second outer coplanar conductors 7, 8, which are arranged after the metallization layer 10, is indicated with the aid of dashed lines.
- the recess 12 has the shape of an isosceles triangle, the top of the isosceles triangle, for example, lying on the center line 13 of the inner coplanar conductor 6 in the plan view.
- FIG. 5 shows a schematic illustration of a side view of the device shown in FIG. 3 for connecting a coaxial connector 1 to a coplanar line 5.
- the substrate support layer 11 has, for example, at the contact point with recess 12 in the metallization layer 10 rectangular cutout 14.
- the surface of the cutout 14 is at least congruent with the surface enclosed by the recess 12 or larger in order to avoid a short circuit at the location of the recess 12 when using a metallic substrate support layer 11.
- the geometric shape of the cutout 14 is arbitrary, it serves only the insulation on the cutout 12.
- cutouts 14 whose edges do not run parallel to one another, ie the width and / or height of the cutout 14 in the substrate carrier layer 11 tapers in the direction along the inner coplanar conductor 6 with increasing distance from the joint.
- FIG. 6 shows, using a first and a second diagram, FIG. 6a / b, the measured reflection behavior and transmission behavior on the device shown in FIG. 3 or on the transition from coaxial plug 1 to co-planar line 5, each with and without a recess 12.
- the use of the Recess 12 in the metallization layer 10 shows the improvement clearly at frequencies above 40 GHz.
- the first diagram in FIG. 6a shows an improvement in the reflection behavior of up to 10 dB at frequencies above 40 GHz.
- the transmission behavior shown in the second diagram in FIG. 6b improves by 1 dB and more at frequencies above 40 GHz.
- a further advantage of the device according to the invention is that commercially available coaxial plug connectors can be used for the implementation, regardless of the substrate support layer 11, the coplanar line 5 and the line geometry of the coplanar line 5.
