A power divider or a power combiner is a device for dividing and/or combining the wireless signals. A power divider is an interdependent device calculating a vector sum total of at least two signals. Power dividers divide power in an input path into two or more output paths. When energy flows in an opposite direction through a power divider, the power divider acts as a power combiner. Power divider circuits are used in radio frequency applications to split an input signal over two or more outputs so that the input signal can be processed in parallel in subsequent stages. RF power dividers make possible the generation of high levels of RF power using lower powered RF transistors. This facilitates the substitution of transistors in place of high-powered tubes, yielding more reliable designs. Microwave power dividers are useful in a wide variety of instrumentation and system applications, such as feeding signals to multiple antennas. Power dividers can also be used to combine microwave signals by applying the signals to be combined to what would normally be considered the outputs of the divider. RF power dividers can be classified into three categories: T-junction power divider, Wilkilson power divider, and Quadratue hybrid power divider. Power dividers are of generally two classes: passive power dividers and active power dividers. Passive power dividers can be designed to work over octave bandwidths with acceptable phase and amplitude control. Active power dividers, which use a three-terminal device such as a transistor for amplification, are less sensitive to input and output matches and can provide controllable gain. A power divider typically includes an internal combustion engine that drives devices such as compressors and pumps.
