考虑了基于一组已知输入端接阻抗的输出功率测量的低噪声放大器关于随机和确定性参数的联合表征。这种方法的优点是,在不需要特殊设备的情况下,可以同时获得窄带和宽带应用的噪声参数和输入阻抗。该方法在数学上得到了发展,并通过仿真和测量得到了实际验证。利用至少四个真实的值随机参数和三个真实的值确定性参数,对放大器进行了表征,并将噪声系数、增益和输入反射作为匹配网络的函数进行计算。网络分析仪、校准噪声源、噪声系数计、滑动螺钉调谐器.),只需一个已知噪声带宽的可调功率计。仅使用四个端接阻抗即可获得四个真实的值噪声参数。使用三个附加端接阻抗即可获得低噪声放大器的输入阻抗。每增加一个端接阻抗,测量的准确性得到提高。异常值被检测并消除。Copyright © 2016 John Wiley & Sons,Ltd.
Joint characterization of low‐noise amplifiers regarding stochastic and deterministic parameters based on output power measurement for a set of known input termination impedances is considered. As an advantage of this method, both noise parameters and the input impedance can be obtained for narrow and broad band applications without special equipment. This method is mathematically developed and practically verified by simulations and measurements. With the knowledge of at least four real‐valued stochastic, and three real‐valued deterministic parameters, the amplifier is characterized, and the noise figure, gain, and input reflection can be calculated as function of the matching network.Two different ways of processing measured data will be shown.Advantages of the proposed method compared with established methods are as follows:No special equipment (e.g., network analyzer, calibrated noise source, noise figure meter, slide screw tuner,…) is needed, just a tunable power meter with known noise bandwidth.The four real‐valued noise parameters can be obtained with four terminating impedances only.With three additional terminating impedances, the input impedance of the low‐noise amplifiers can be obtained.With every additional terminating impedance, the accuracy of the measurement is improved.Outliers are detected and eliminated.Copyright © 2016 John Wiley & Sons, Ltd.
