An equivalent circuit analysis including meander electrode resistance is applied to an acoustic coupler which has been proposed using cascaded quadrature wavelength group-type unidirectional structure. Linear circuit composition procedure for multi ports elements is applied in order to explain the meander resistive effect. Cascade-connected ports are prepared for the meander electrode. The experimental results was found to be in good agreement with the improved circuit calculation.
