ADVANCED INFORMATION
APPLICATION INFORMATION (CONT.)
In conclusion, the ability to provide a clean signal during transmission/reception can be done with linear regulators in a
predictable way, the novelty comes in considering the Buck and Linear concept which has the advantage of high
efficiency while not compromising the linear regulator’s low noise characteristics.
The overall effect being longer battery life while maintaining low RF interference in a wireless system.
