RF Power Dividers/Splitters

1. What are RF Power Dividers/Splitters?

An RF power divider (also known as a power splitter) is a passive device that splits an input signal into two or more output signals of equal amplitude and phase. It is used to create multiple signals of equal power levels from a single source. RF power dividers are commonly used in radio frequency (RF) systems, such as cellular networks and radio transmitters. They are also used in radar systems, satellite communications systems, and other telecommunications systems.

 

2. How do RF Power Dividers/Splitters Work?

An RF power divider works by splitting the input power into two equal parts and sending each part to one of two outputs. This device is typically passive, meaning it does not require a power source to operate. Signal division can be achieved using a directional coupler or a resistor network. In a directional coupler, the input signal passes through a pair of transmission line elements and is then coupled together. This coupling causes the signal to be split into two parts, each of which is sent to one of two outputs. A resistor network is used to split the input signal into two or more output signals.
