Balun Transformers
Passive devices that convert between balanced and unbalanced signals
A balun transformer bridges the gap between balanced differential signal lines and unbalanced single-ended connections, ensuring efficient power transfer with minimal signal loss. These components play a critical role in RF front-end designs, where an RF balun transformer matches impedance between antennas and transmission lines while rejecting common-mode noise that would otherwise corrupt the received signal. Performance parameters like insertion loss, return loss, bandwidth, and phase balance determine how well a given balun transformer fits a particular frequency and application. We list balun transformers from leading passive component manufacturers, allowing you to review datasheets, check up-to-date availability, and compare pricing across authorized distributors.
