FAQs - Cryogenic Low Noise Amplifiers

Product Specifications & Performance

Our LNAs offer ultra-low noise performance - for instance, the LNF-LNC1.2_3.5A achieves 1.3 K, and the LNF-LNC 4_8G is 1.5 K, with variations across models.

Gain varies by model; for example, the LNF-LNC1.2_3.5A delivers 31 dB, and the LNF-LNC 4_8G reaches 40 dB.

Bias requirements vary by model. For example, the LNF-LNC4_16SB requires 1.1 V, 16 mA, and the LNF-LNC4_8F_LG requires 0.7 V, 10 mA.

All LNAs are tested at 4 K (and in some cases 5 K) and are guaranteed for reliable cryogenic operation.
