Low-noise amplifier (LNA) is an electronic amplifier used to amplify possibly very weak signals (for example, captured by an antenna). It is usually located very close to the detection device to reduce losses in the feed line. This active antenna arrangement is frequently used in microwave systems like GPS, because coaxial cable feedline is very lossy at microwave frequencies, e.g. a loss of 10% coming from few meters of cable would cause a 10% degradation of the signal-to-noise ratio (SNR).
Measuring at cryogenic temperatures
Using The CryoLab, it is possible to measure the performance of a LNA from room temperature down to cryogenic temperatures. Cooling it down to cryogenic temperatures highly improve the signal-to-noise ratio of the LNA, increasing its sensitivity. The LNA can be connected to a carrier chip to which electronic connections can be made using bond or solder wires. Measurements can be done fast and in a plug-and-play manner. Once the LNA is optimized for cryogenic temperatures, integrated solutions or CryoCube developments could be considered to realize in-field applications.
