Keywords: cryogenics, receivers, infrared filters
Thermal loading of cryogenic receivers is often dominated by infrared radiation accompanying the desired signal. This loading can be minimized by low-pass filters in the signal path. Here the use of multiple layers of thermally isolated materials is investigated for this purpose. Measurements of several materials are reported and compared with calculations.
