Abstract

This paper presents a set up and a measurement data processing method applied to the characterization of non linear power amplifiers driven by Galileo modulation schemes for radio navigation application. The work reported here focuses on the impact of power amplifiers with memory on autocorrelation losses of Galileo signals. A hybrid MESFET amplifier having 17 dB power gain, 1 watt output power and 60% PAE has been characterized at 1.19 GHz with a signal bandwidth varying from 100 KHz to 80 MHz.
