The problem of electrodynamics and circuitry modeling of a three-stage three-decibel microstrip directional coupler with phase-shifting circuit between sections is considered. The aim is to research the original design solutions of three-stage directional couplers with a phase-shifting circuit between quarter-wave sections. The possibility of eliminating jumpers between sections due to the use of phase-shifting circuit with distributed and lumped parameters to increase the manufacturability and stability of the parameters of directional couplers with strong coupling is justified. The correctness of the simulation results obtained is con firmed by a comparative analysis of machine experiment data and the introduction of directional couplers into the submodules of power amplifiers of L, S and X-ranges.
Key words: directional coupler, electrodynamics and circuit modeling, phase-shifting circuit with distributed and lumped parameters, data from a machine experiment, divider–combiner power, submodules of power amplifiers of L, S and X-band.
