    Article
    Open Access
    An analysis of the problem of noise parameter determination is carried out. It is found that the mathematical problem is ill-posed if all the source reflection coefficients (Γs) used in the measurements fall onto a line, ...

  • Method for measuring noise parameters of microwave two-port 

    Lázaro Guillén, Antoni; Pradell i Cara, Lluís; O'Callaghan Castellà, Juan Manuel (IEE, 1998-06-30)
    Article
    Open Access
    A new tuner-based method for measuring the four noise-parameters of a two-port is proposed. It makes use of a novel measurement ratio that includes noise powers and mismatch factors simultaneously. In contrast to previous ...
