ABSTRACT:

BACKGROUND OF THE INVENTION
The present invention generally relates to arrangements.
More particularly, it relates to an arrangement for producing electronic oscillations in a Giga hertz region in high frequency circuits (f>50 GHz). Gunn elements are used for generation of oscillations. They are arranged in a housing. The electrical contact between the Gunn element at the inner side of the housing cover must be designed flexibly, since because of the heat produced in the Gunn element, relatives movements between the Gunn elements and the housing occur. Conventionally, the contact between the Gunn element and the housing cover is produced by a so-called bonded Maltese cross. This type of the electrical connection is however difficult to reproducibly manufacture and in a long-term service is not always reliable. It should be noted that due to the small housing dimensions and Gunn element dimensions, a reliable contacting is very difficult.
SUMMARY OF THE INVENTION
Accordingly, it is an object of the present invention to provide an arrangement of the above mentioned general type, which avoids the disadvantages of the prior art.
In keeping with these objects and with others which should become apparent hereinafter, one feature of present invention resides, briefly stated in an arrangement for producing electrical oscillations in Giga hertz region, in which between a contact surface of the Gunn element and the housing cover, an elastic, electrical contact element is clamped.
When the arrangement is designed in accordance with the present invention it has the following advantages. It can be produced with small housing and Gunn-element dimensions, in particular in a Giga hertz region above 50 GHz in an easily reproducible process. In a long-term operation it operates reliably to compensate the relative movements between the Gunn elements and the housing cover.
