Problem statement. The values of the output power of the microwave channels of the transceiver modules located in the APAA hole have a large spread, which leads to an uneven distribution of the amplitude over the aperture. An urgent task in the design of APM and APAA in general is to determine the maximum achievable radiated power and obtain a uniform amplitude distribution due to the maximum possible narrowing of the range of the output power spread of microwave channels.

Goal. To propose a method for obtaining the maximum achievable average radiated power of the APAA, taking into account the limitations of the power supply system and the cooling system by stabilizing the output power of the microwave channels RTM. Results. A method of designing an APAA is proposed to obtain a uniform distribution of the amplitude over the APAA aperture and determine the maximum achievable total power of the APAA radiation.

Practical significance. The proposed method allows us to design an APAA with the maximum achievable total radiated power.
