Basic characteristics of quantum paramagnetic amplifiers

  • Published:
Measurement Techniques Aims and scope

Conclusions

It is advisable to consider as basic those characteristics of a maser whose aggregate completely determines the properties of a maser in its practical application (as an amplifying stage in a receiving system), and whose values can be measured directly. Such characteristics include the amplifier frequency range, amplifier gain, bandwidth, noise temperature at the amplifier input, saturation power, gain instability, and decoupling. Another group of characteristics which can be measured directly is of no particular interest, and includes the restoration time and losses of the amplifier.

Finally, a third group of characteristics which are of specific interest and can be determined unambiguously, provided the characteristics of the first two groups are known, includes the paramagnetic amplification factor, resonant maser efficiency, and maser sensitivity and dynamic range.
