Abstract :
This article presents a design methodology for low noise amplifiers (LNA) in the UHF band, optimized for narrowband operation, based on a proper choice of the bias operating point, modeling of the active element through S parameters and the appropriate design of matching networks for minimum noise figure and maximum gain under stable conditions. Likewise, presents a case study related with the design of an LNA with this methodology, together with the experimental results and the results simulated with the Ansoft Designer® platform.
