Recently more attention is paid to unmanned aerial vehicle radio-electronic systems. The X-band amplifier with power output of the order of hundreds of watts can be constructed by power combining of several ten watt class amplifiers. Several possible implementations of a power X-band amplifier with few parallelly concatenated amplifiers have been analyzed. According to the results of the EM-based modeling in CAD environment based on numerical methods for solving the finite element method, advantages and disadvantages each of these implementations were reported.
