With the move to millimeter wave in 5G and Satellite communications, transceiver designers are faced with increasing challenges to differentiate their products. Characterizing the noise contributed by RF and microwave amplifiers and frequency converters is essential for optimizing overall system performance. Noise figure, the accepted figure-of-merit, is typically measured using the widely-understood Y-factor or hot/cold method. However, when using a vector network analyzer, the less-familiar cold-source method lends itself to advanced error-correction techniques that enable exceptional measurement accuracy. This webcast will provide an overview of both techniques and contrast their strengths and accuracy limitations.
