Abstract

A base comprising a metal mounting stud to which is fixed a locally metallized insulating plate of the beryllium oxide type. In order to very accurately position active or passive component or components on the insulating plate, at least one connecting electrode comprises at least one abutment zone against which is placed at least one component. This makes it possible to obtain a very good reproducibility of the electrical performances of the device. Such a mounting is applied to ultra-high frequency devices, particularly those incorporating a pre-matching circuit.
