A 24-channel Ku-band power divider for active phased antenna array has been proposed and developed. The divider is built using a tree network with 1×3×2×2×2 structure, while all its elements are implemented using a finline. As a result, additional insertion loss of the manufactured specimen amounted to 1.8 dB that corresponds to the efficiency of about 66%. The measured isolation of the divider outputs amounted to no less than 16 dB for any pair of channels with the irregularity of power division between channels of no more than 0.3 dB in the working frequency range of 9–14 GHz.
