The optimum trade-off performance of an LNA for VSAT applications based on a commercial pHEMT series have been investigated vs. temperature, starting from a noisy model fitted to the measured devices scattering parameters and noise figure values. As a result, it has been noted that with decreasing the temperature from the room value, the combined Fmin-Gass, reported on the microwave low-noise device's data sheets, doesn't represent an useful working condition for an optimum LNA design.

Abstract
The optimum trade-off performance of an LNA for VSAT applications based on a commercial pHEMT series have been investigated vs. temperature, starting from a noisy model fitted to the measured devices scattering parameters and noise figure values. As a result, it has been noted that with decreasing the temperature from the room value, the combined Fmin-Gass, reported on the microwave low-noise device's data sheets, doesn't represent an useful working condition for an optimum LNA design.File in questo prodotto:
