    • The 6.5 dB optical losses consist of 3.3 dB for the beam splitter, window, and heat filters (measured values), 1.1 dB for lens reflection, 1.2 dB for lens absorption and lens/antenna mismatch, and 0.9 dB for the air path between the hot/cold load and the cryostat.

    • Note that a type I device of another batch with the same geometry, but with a resistance at 20 K of 157Ω has shown a receiver noise temperature of 2800 K using the identical measurement setup.

    • The device quoted in Ref. 15 would have given a receiver noise temperature of 1400 K if it was measured using the same optimized setup as used for Dl of geometry III quoted here.

    • The results in Fig. 2 are obtained between 0.1 and 6 GHz. Higher frequency measurements are not possible in our present setup.
