The array antenna structure with digital beamforming was considered. The basis of its construction is the transceiver module, which is involved in active adaptive array antenna aperture forming. Power amplifier is the main element in digital transceiver module's transmission path. The PA should provide both high power gain and efficiency and be of small size and weight. GaN field-effect transistor power amplifier model was developed thus improving the efficiency of transceiver module.
