In many communication transceiver designs, an unbalanced single-ended signal must be converted to a balanced differential signal. This task is often considered routine, and a flux-coupled transformer ...

Balun bandpass filters represent a critical advancement in radio frequency (RF) circuit design, integrating the dual functions of balanced-to-unbalanced conversion and frequency selection. These ...

This chapter excerpted from Sevick’s Transmission Line Transformers describes the balun as a subset of transmission line transformers with an in-depth treatment of most used types. Schematics and ...
