What Is a Bias Tee?
A bias tee separates direct current (DC) and alternating current (AC) in electronic circuits.
It introduces DC power to components needing biasing while allowing AC signals to pass without interruption. The device ensures that DC and AC paths are isolated, preventing noise from the DC source from impacting the AC signal. This feature is crucial in applications where signal integrity is vital.
Bias-tees are essential in powering amplifiers and RF filters, and they play a significant role in testing and measurement scenarios across various electronic disciplines.
