Abstract :
The variant of modification of a two-branch-line directional coupler for operation in two aliquant frequency bands is offered. Unlike the known constructions only two additional reactive elements are used at that. The possibility of two-band operation of branch-line coupler without reactances utilization is investigated. The analytical correlations for the calculation of electrical parameters of such couplers equivalent circuit elements are obtained.
