Power Dividers vs. Power Splitters: What’s the Difference?

What happens when you have more objects in need of power than you have power sources? At home, you probably go find an extension cord. When you’re on the job, you need to be a bit more precise. This means choosing between power dividers and power splitters. These tiny silver boxes may look very similar and even do similar types of jobs, but the truth is they have different characteristics that determine which tasks they are best for.

The Power Divider

Dividers like the RF power dividers are components used to divide a power source equally between the output signals. Typically, these dividers consist of three resistors that are best used for systems of testing and measurements. These types of dividers can also act as power combiners when needed. Although 3-way dividers are most common, you can also find them in 4-way, 6-way, 8-way, and 12-way ports, depending on the number of Ohms provided with the product.

The Power Splitter

Power splitters usually use two-resister models. These types of splitters are used for leveling loop measurement and create better source matching. These splitters are great for testing gain and power, as well as leveling and ratioing.

How Dividers and Splitters Work

Power dividers and splitters are responsible for separating an incoming signal into multiple outputs. Dividers are known as reciprocal networks and some dissipation of power is to be expected. When choosing which types of dividers you need, consider the isolation. High isolation prevents signals from interfering with each other, for example.

When choosing the right splitters or dividers for your job, be sure to purchase from a reputable manufacturer. This prevents you from buying faulty products and ensures you have exactly what you need to complete your projects. Remember to compare prices and return policies to make sure you get the best deal.
