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. |
