Abstract

The Discrete-Time Convolution Model behavioural approach is proposed for the characterization/empirical modelling of high-performance broad-band A/D channels, designed for the acquisition of signals approaching the microwave field. Thanks to its inherent capability of separately describing all the non-idealities of different nature within the channel, and in particular the non-linear dynamic effects, the method is particularly suitable for the A/D channels of modern high-frequency instrumentation and RF receivers. Experimental results are provided, which validate the analytical formulation of the approach and the related measurement procedures/set-ups for model parameter experimental extraction, for a state-of-the-art, 1-GHz analog bandwidth 1-GSa/s A/D acquisition channel for satellite radar applications.
