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 the 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 the normalized negative conductance, the relationship between the gain and the effective noise figure is thus found. An upper limit of the bandwidth of the amplifier is established in view of the optimum noise performance. Finally, a method of synthesis is suggested with numerical illustrations.

本文首先推导了级联着一个噪声很高的次级的参量放大器系统的有效噪声系数,并且用耦合系数和规一化负电导来表示;然后详细地讨论了这个有效噪声系数的最佳化问题。因为放大器的增益也可用耦合系数和规一化负电导来表示,因此在增益和有效噪声间获得一个单值关系式。从最佳噪声运用角度出发建立了放大器通带的上限值。最后,提出一个新的综合方法,并用数字例子作说明。
