Abstract (en)

The microwave coaxial line has an inner conductor (1) and an outer conductor (2). The thermal conductivity of the coaxial line is reduced whilst maintaining the effective electrical length by increasing the effective thermal length of the inner conductor and/or the outer conductor and/or the effective thermal cross-section is reduced whilst maintaining the effective electrical cross-section. At least one pair of hollow conductors (5-1,5-2), one inside the other and shorted at the ends, is attached to the inner and/or outer conductor as an extension line.

Abstract (de)

Bei einer Mikrowellen-Koaxialleitung für gekühlte Mikrowellensysteme mit einem Innenleiter (1) und einem Außenleiter (2) ist zur Verringerung der thermischen Leitfähigkeit der Koaxialleitung die thermisch wirksame Länge des Innenleiters (1) und/oder des Außenleiters (2) unter Beibehaltung der elektrisch wirksamen Länge vergrößert und/oder der thermisch wirksame Querschnitt des Innenleiters (1) unter Beibehaltung des elektrisch wirksamen Querschnitts verkleinert. Die Koaxialleitung weist eine minimale Dämpfung bei gleichzeitig maximalem Wärmewiderstand auf. <IMAGE>
