Simple and Accurate Method for Microwave Noise Parameters Calculation
MetadataShow full item record
This paper proposes a new method for microwave two-port noise parameters values extraction. The method is based on a set of simple and accurate formulas witch allows the noise characterization without any optimization procedure. The measurements were performed using a system based on a short cascaded with a long transmission line and a passive two-port designed to exhibit versus frequency a behavior close to a transistor. The results presented for a measurement example show good agreement with those obtained using an optimization procedure. The new extraction method based on the frequency variation noise measurement principle and used with a simple hardware can be a practical tool for workers in the field.
