Abstract:
The complexity of the transmission and reception paths and especially antenna systems for satellite and mobile communications require improvement of existing and creation of new methods for modeling of nonlinear devices. In the last 20-25 years attention to the problems of calculation and technologies of building of active antennas, especially multibeam active phased antenna arrays (AРAR), including nonlinear model modules solid-state power amplifiers (SSPA) transmitters has changed significantly. AFAR for various ranges have been analyzed to study the nonlinear effects and the results have been compared with experimental data.
