Optimizing On-Wafer Noise Figure Measurements up to 67 GHz
Two techniques are commonly used to measure NF: the Y-factor method and the cold-source method. The Y-factor or hot/ cold-source method is the predominant approach and is most commonly implemented with noise-figure analyzers and spectrum analyzer-based solutions. In contrast, the cold-source method is usually performed using vector network analyzers (VNAs), which provide magnitude and phase inf...

These poets try to be inventive in order to escape banality and repeated and shallow literary traditions, and by creating a rift between themselves and former traditions they introduce new elements. These artists either create new figures o...
متن کاملFamilial goiter in bongo antelope (Tragelaphus eurycerus).
Congenital defects in thyroglobulin (Tg) synthesis in animals have proven to be useful models for the study of Tg synthesis and regulation. Defects in Tg synthesis have been well described in Afrikander cattle, Australia Merino sheep, and goats in The Netherlands. This report describes a study of goiter in a nondomesticated bovine species, bongo antelope (Tragelaphus eurycerus), an African bovi...
متن کاملFigure Captions. Figure 1. an Example of a Domain
An e cient multigrid approach for solving a discretized elliptic equation whose boundary values are determined in part by integral relations is developed, analyzed and tested. The algorithm is implemented on a problem that is solved during integration of the three-dimensional Quasigeostrophic equations, which model large-scale rotating strati ed ows, where the integral constraints represent mas...
