How does a power splitter work?

A power splitter, also known as a power divider, is an electronic device used to divide an input signal into multiple output signals with equal or unequal power levels. It is commonly used in various applications, such as telecommunications, radio frequency (RF) systems, and audio distribution systems.

The basic principle of a power splitter involves the use of passive components, such as resistors, capacitors, and inductors. There are different types of power splitters, but the most common one is the resistive power splitter, which uses resistors to divide the power.

When an input signal is applied to a power splitter, it is divided into multiple output signals. In a resistive power splitter, the input signal is connected to a network of resistors in a specific configuration. The resistors are designed to have equal resistance values, which ensures that the power is divided equally among the output ports.

The power splitter can be designed to have different power division ratios depending on the application requirements. For example, a 2-way power splitter divides the input power equally into two output ports, while a 3-way power splitter divides the power equally into three output ports, and so on.

In addition to resistive power splitters, there are other types of power splitters, such as Wilkinson power splitters and hybrid power splitters. These types use different configurations of passive components to achieve power division.

Overall, a power splitter works by using passive components to divide an input signal into multiple output signals with equal or unequal power levels, depending on the design and application requirements.
