Abstract
A dual output autotransformer is realized by employing a novel topology in which three transformers are wound on a single, high permeability, ferrite, binocular core. The three transformers are (1) an autotransformer; (2) a coupled winding to the autotransformer; and, (3) a transmission line transformer. Within the topology employed, the outputs of the coupled line transformer and the transmission line transformer provide the balanced output (secondary) and the input to the autotransformer forms the unbalanced primary. Such an approach results in a wideband response of from 30 MHz to 3000 MHz or greater with the requisite amplitude and phase balance.
