RATAN-600 continuum radiometers are placed in two HF feed cabins:
N1 and N2. The complex consists of 12 radiometers in the wavelength range
from 1 to 49 cm. Radiometers are used for convenience observations of radio
sources. Complexes of continuum radiometers in recent years undergone
considerable renovation.
Due to the repetitive use of the resource of the cryogenic systems and
the impossibility of mass purchasing a new cryogenic equipment,
RATAN-600 cooled low noise amplifiers (LNA) in radiometers are replaced
by "warm", that is operating without cooling.
