LOW CROSSTALK REVERSED .BETA. ELECTRODES FOR DIRECTIONAL COUPLER SWITCH

摘要

LOW CROSSTALK REVERSED .DELTA..beta. ELECTRODES FOR DIRECTIONAL COUPLER SWITCH Crosstalk for a directional coupler switch employing a reversed .DELTA..beta. electrode structure is reduced to a minimum by properly placing electrode sections over the waveguides to compensate interwaveguide coupling preceding an electrodesection with interwaveguide coupling following the electrode section.
