Abstract:

The effective noise figure of a nondegenerative parametric amplifier, loaded with a noisy second stage, is derived and expressed in terms of the coupling factor and normalized negative conductance. The optimization of the effective noise figure of the system is then discussed in detail. The gain of the amplifier is also given in terms of the coupling factor and normalized negative conductance. In this way, the relationship between the gain and the effective noise figure is found. An upper limit of the bandwidth of the amplifier is established in relation to the optimum noise performance. Finally, a method of synthesis is suggested. Author
