RF power dividers and splitters are an essential part of many communication systems. They are used to divide and direct radio frequency signals (RF) signals, typically from an antenna, to several receivers. Multi-port networks have applications in many areas, including broadcasting, cellular telephone networks, instrumentation and test equipment.

A power divider is a passive device used to divide or split a transmitted signal into multiple parts. It can also be used to combine several signals into one. Power dividers are commonly used in wireless communication systems to separate a signal into individual parts that can be used to send the signal in different directions or on different paths. This allows multiple users to use the same frequency without interference.

A power divider is based on the principle of reciprocity. This means that it can also be used to combine multiple signals into one, making it bidirectional. A common type of power divider is the Wilkinson power divider, which is a non-directional passive device that can be used to divide or combine signals. It is made up of two transmission lines, which are connected to each other in a circular loop. The signals are divided by the impedance of the lines, which can be adjusted by changing the length of the lines. The Wilkinson power divider is a popular choice because of its wide frequency range and low insertion loss.

Power dividers come in many different configurations. An example of a popular configuration is the 4:1 power divider. This is a passive device consisting of four inputs and one output. Each input is connected to one of the output lines, and the combined signals are then sent to the output. The 4:1 power divider can also be used in reverse to combine signals into one. This type of divider is commonly used in systems such as cellular telephone networks to divide the signal from the base station among several users.

Power dividers are also used for other applications such as match-networking, antenna matching, high power, narrow band and wideband applications. In matching-network applications, power dividers are used to match the impedance of the antenna to the input port of the matching-network. This ensures the highest signal transfer from the antenna to the receiver. In antenna matching applications, the power divider is used to match the antenna to the radio transmitter. This ensures the maximum signal strength is transferred to the antenna. In high power applications, the power divider is used to minimize signal loss and increase signal gain. In narrowband applications, the power divider is used to separate narrowband signals from wider bandwidth signals. Lastly, in wideband applications, the power divider is used to create multiple paths and combine multiple signals into one signal.
