The Two Main Types of RF Power Dividers

Business , Technology May 14, 2019 No Comments

An interest in electronics can take you far, from a weekend hobby soldering a circuit board together to an immersive profession in engineering. No matter your level of experience, you may come across RF power dividers as you work. These handy devices help to divide the energy of a main line of power into multiple smaller lines. There are two types of categorization used to describe RF power dividers, so keep reading in order to recognize them in the future.

RF Power Dividers

Hybrid Power Splitters

The hybrid power splitters are a type of RF power divider that functions by way of energy transformers. This means that these power dividers have a lower level of energy loss than other types of power dividers. The majority of this loss is centered around the process of power splitting. It can sometimes be a higher amount of loss if there are more output ports rather than less output ports.

Resistive Power Splitters

Resistive power splitters operate by using resistors to split the energy of the main line towards the output ports. One great aspect of the resistors is that they are inexpensive to produce as well as simple to create. However, the resistors do cause more energy loss than other types of power dividers. This may be an important factor to remember as you plan the building of your electrical systems.

An Early Version of the RF Power Divider: The T-Junction

In the nascent years of power divider development, basic T-junction devices were used to split one energy line into two energy lines, forming a T-shaped pathway for the power to follow. While functional, these devices suffered from large losses of energy as well as the inability to keep energy from reflecting back from one output port into the other output port. Due to the unreliability of past designs, modern types of efficient power dividers are preferred.
