Many of today\'s radars are primarily designed with sophisticated RF apertures, among them AESA. A review of development trend of transmitter modules for AESA suggests that its capability enhancement is made possible by updating of solid-state hardware components. The article introduces design of UHF-band AESA-s transmitter modules for current and future radars. These modules provides high ef-ficiency throughout the range of power outputs, high stability of the set output power and output phase in all conditions, availability of flexible system of digital control. It is made possible by using of modern hardware components and new technical solutions. At the same time a feature of developed transmitter module is possibility of automated calibration when serial production. Also the article describes a block scheme of transmitter module. It consists of a prime amplifier with control function, a power divider, high power output amplifiers, a power combiner and a power supply system. The results of transmitter module-s demonstrated optimization have been introduced in this article. Efficiency factor and output power of the RF power amplifier in the frequency band have been showed. The article notes that the materials of this article can be useful in the development of current and future radars with both diffuse and point source transmitting paths.
