Broadband balun structures and applications thereof

Abstract

The present disclosure provides a new broadband balun structure, comprising an inverting transformer and an autotransformer; wherein the inverting transformer is configured to invert an input signal to generate an inverting signal; the autotransformer is configured to divide the input signal to generate an in-phase signal; at least one of one end of the inverting transformer or one end of the autotransformer is connected to an unbalanced end; the inverting transformer is connected to the autotransformer when the one end of the inverting transformer or the autotransformer is connected to the input signal of the unbalanced end; and the other end of the inverting transformer is used as an inverting signal end of a balanced end, and the other end of the autotransformer is used as an in-phase signal end of the balanced end.

Dependencies are inferred from the claim text.
