Abstract
Circuit arrangement with a contact element that electrically connects a waveguide 1 to a stripline 7 of a strip transmission line. In order to ensure a reliable electrical connection, even when the waveguide 1 and the stripline 7 have different rates of thermal expansion, the contact element has an electrically-conducting housing 3 and therein a bundle 4 made of an electrically-conducting thread or tape e.g. wire wool, the housing 3 being glued in an electrically-conducting manner to the stripline 7 and the bundle 4 being resiliently pressed against the waveguide 1.
Description
Circuit arranizement
Prior art
The M'venfion is based on the genre as specified in the independent Claim 1.
In microwave circuits for the frequency range above 50 Ghz,-so-called tapped transformers, whose geometry is substantially determined by the wavelength of the frequencies in use, are employed at the junctions between waveguides and stripline circuit components.
An electrical connection is usually required from the final stage of the tapped transformer to the stripline circuit arrangement. This connection is realised by means of small conductive gold strips, for example, these small strips being placed either diagonally or on the underside of the final stage. This method of manufacture is very costly. The electrical connection is also seriously mechanically stressed by possible relative movements due to different thermal expansion rates of the metallic waveguide and dielectric stripline substrate.
Advantages of the invention The subject-matter of the application with the features of Claim I has the following advantage:
It can be easily manufactured. Different thermal expansion rates are satisfactorily compensated.
Advantageous developments, whose features can also be taken in combination where practical, are stated in the dependent claims.
Drawing An exemplary embodiment of the invention is illustrated in the drawing and described in more detail below. Figure I shows schematically a greatly enlarged partial section through a circuit arrangement according to the invention.
Description of the exemplary embodiment
A waveguide I in the form of a tapped transformer and a stripline substrate 2 rest on a metal plate 5. The waveguide is screwed to the metal plate 5. The arrangement as a tapped transformer is not shown in further detail. The stripline substrate 2 is glued on with the aid of an electric ally-conducting adhesive material 6. The stripline substrate 2 is provided on its upper side with a striplMie 7. This is a constituent part of a microwave IC (MIC). The waveguide I has a coupling aperture 8 in the vicinity of the striplMie.
The electrically-conducting housing 3 of a contact element is mounted on the stripline 7 by means of electrically-conducting adhesive material 9. A bundle 4 made of metal wool projects from the housing 3. Housing 3 and bundle 4 together form a so-called Chinch contact. Following the gluingon of the housing 3, the waveguide I has been mounted so that the contact element with its electricallyconducting bundle 4 presses resiliently against one face of the tapped transforTner of the waveguide 1, this face being substantially perpendicular to the plane of the stripline. The lowresistance contact between the waveguide I and the stripline 7 is established by means of the contact element. This low-resistance connection is necessary in order to enable the electromagnetic wave from the waveguide I to be injected into the stripline 7 in an optimally-matched manner. At the same time, a matched geometry of the junction also plays a decisive role.
With the aid of the elastic bundle 4 it is also possible to compensate for relative movements between the waveguide I and the stripline 7. The housing 3 receives the bundle 4 and establishes the conducting connection to the stripline 7.
Possible modifications The form of the Chinch contact is shown only schematically. It can vary.
