Abstract

In a cooling apparatus for a high-frequency receiver having an input circuit which carries signals that are not yet sufficiently amplified, the input circuit is thermally connected to a miniature cooler and is thermally insulated, including a cold output of the miniature cooler, from the environment. It is particularly favorable if the miniature cooler has no moving parts on the cooling end. The miniature receiver is preferably configured as a pulse tube cooler.

Claims

1. A cooling apparatus for a high-frequency receiver having an input circuit which carries signals that are not yet sufficiently amplified, the apparatus comprising:

a pulse tube miniature cooler thermally coupled to the input circuit;

wherein the input circuit and a cold output of the miniature cooler are externally thermally insulated.

2. The cooling apparatus according to claim 1, wherein the input circuit includes an input filter.

3. The cooling apparatus according to claim 1, wherein the input circuit includes a transistor.
