Modelado y simulación realista del módulo posterior de un radiómetro: aplicación al instrumento a 31 GHz del experimento QUIJOTE

Abstract

In the reported work, an efficient modelling method is applied to the circuits of the 30 GHz Back End Module of the QUIJOTE experiment radiometer. In particular, efficient models of two LNAs, a band pass filter and a detector has been obtained. These models allow realistic time-domain BEM simulation by using Gaussian noise excitation signals. Simulation results have been reported, showing good agreement with the BEM expected operation. On the other hand, time-domain realistic simulations will provide valuable information about BEM behaviour previously to the receiver definitive implementation.
