Abstract
The crosstalk caused by a slight longitudinal misalignment of reversed-Δβ electrodes on directional coupler switches is investigated. We show that this crosstalk can be reduced or eliminated by use of independent voltage adjustment of the two electrode sections. The displacement must be maintained below 1.5% if the magnitudes of the two required voltages are not to differ by more than 10%.
