In noise measurement the problem of noise transmission in the two-port networks in cascade is frequently met with. Each stage of the network itself will contribute its noise whereas it will Jose the noise power transmitted from the former stage. The noise can be exactly measured only when its loss and contribution in the network have been defined.This article analyses the loss and generation of noise in the network by means of the concept of the available power transmission coefficient, and derives the formula...

In noise measurement the problem of noise transmission in the two-port networks in cascade is frequently met with. Each stage of the network itself will contribute its noise whereas it will Jose the noise power transmitted from the former stage. The noise can be exactly measured only when its loss and contribution in the network have been defined.This article analyses the loss and generation of noise in the network by means of the concept of the available power transmission coefficient, and derives the formula for noise transmission in the lossy . two-port networks in cascade. This formula has been applied to determine the available noise temperature of the thermal noise standard source.

噪声在级联二端口有耗网络中传输时,每一级网络除了损耗前一级传输过来的噪声功率外,还要给出网络本身的噪声。只有确定了网络中损耗和发生的噪声,才能准确地进行噪声测量。 本文利用资用功率传输系数概念来分析网络中噪声的损耗和发生,推导出级联二端口有耗网络中噪声传输的计算式。该计算式已被用于确定热噪声标准源的资用噪声温度。

A method for the noise analysis of microwave amplifiers is developed. A set of transformation formulas for the equivalent noise parameters of the amplifiers with feedback, lossy matching, and other circuits are given. The formulas which take into account the noise source of all circuit elements are used in computer aided noise analysis program.

The effect of lossy series-network on the signal and noise parameters of low noise GaAs FET's and the conditions for simultaneously achieving noise and power match are discussed in detail in this paper.

本文详细讨论了有耗串联网络对低噪声GaAs FET的信号参数和噪声参数的影响,以及同时获得噪声匹配和功率匹配的条件。以WC606型GaAs FET为计算实例表明:在频率为12GHz,当串联电感为0.1nH,负载反射系数为0.25∠120°时,可以同时获得噪声和功率匹配。但此时最小噪声系数将增加0.2dB,而相应增益下降1.0dB。
