The method of optimal choice of geometric values for directional couplers with strong coupling has been proposed, which makes it possible to shorten the processing time while maintaining specified accuracy. The method is based on the decomposition of the device under study into composite elements which electrical parameters are determined analytically or by numerical algorithms. The proposed approach for calculating directional couplers is based on analysis of the results obtained with combinations of the most probable variants of directional coupler design variables. These combinations are formed during the composition of a directional coupler from elementary blocks (communication elements). The projection of this method for its use in conjunction with CAD for electrodynamics modeling has been given. The advantage of the proposed method of calculation is significant reduction in the calculation time without reducing the accuracy, as well as the ability to obtain directional couplers with better characteristics.
