本文介绍了一种适用于大信号条件下微波器件噪声参数测量的装置。该方法是基于多阻抗技术和测试集已被修改，包括泵发生器。还存在适当的低通滤波器，以避免不同测量设备的饱和。在两个不同的放大器上获得的结果显示出良好的一致性，从残余相位噪声测量提取的实验数据。因此，该测试装置可用于设计低相位噪声放大器
A noise parameter measurement setup dedicated to microwave devices operating under large-signal conditions is presented in this paper. The method is based on the multiple impedance technique and the test set has been modified to include a pump generator. Appropriate low-pass filters are also present in order to avoid the saturation of the different measurement apparatus. The results obtained on two different amplifiers show a good accordance with experimental data extracted from residual phase noise measurements. This test set can thus be used to design low phase noise amplifiers
