Abstract
The invention relates to an HF terminating impedance in strip conductor technique in which the resistive layer is enclosed between two ceramic plates which are clamped from the outside by metallic heat dissipating plates, the freedom from reflection of the terminating impedance being ensured by the lateral edge lines of the resistive layer satisfying the condition ##EQU1## To ensure an intimate heat conduction contact between the resistive layer and the ceramic plates and the ceramic plates and the adjoining clamping plate without introducing bending stresses into the ceramic plates which might cause fracture, at the contact surfaces a soft metal foil, preferably of lead, is inserted which is prevented from cold flow by a rolled-in grating or netting, in particular of bronze or copper. The ceramic plates may be made plane parallel (for smaller powers) or wedge-shaped, by which the advantage can be achieved that per unit length substantially the same power density is obtained and because of the favorable heat dissipation via the ceramic plates and the metal plates clamping them a high permanent power can be taken up with compact construction.
