A Receiving Device of the Spectrometer at 21-CM Wavelength
Abstract
A description of the receiving device at 21 cm wavelength of the spectrometric complex of the radio telescope RATAN-600 is presented. At the input of this device a transistor amplifier performed in hydrid-integral design and cooled up to the temperature of liquid nitrogen is used. The noise temperature of the receiver does not exceed 40K. Measurement methods with the noise pilot-signal is described.
