A floating decoy adapter for land use includes an attachment plate, a vertical support plate and a base section. The current mode control loop includes a current feed-forward to reduce a load dependence of a loop gain by reducing a load current dependence of a low frequency component of a gain of the error voltage to the output voltage with a current loop closed. The anode electrode of the optical modulator element and one of the ends of a terminal resistor element are connected by a second bonding wire.
