Description

Technical Field

[0001] The invention relates to the technical field of electronic components. Background Art

[0002] A power divider is also called a power splitter. It is a device that divides the energy of an input signal into two or more equal or unequal outputs. It can also combine the energy of multiple signals into one output. In this case, it can also be called a combiner. A certain degree of isolation should be guaranteed between the output ports of a power divider. It is also called an overcurrent distributor. It is divided into active and passive types. It can evenly distribute one signal into several outputs. Generally, each divided signal has a few dB of attenuation. The signal frequency is different, and the attenuation is different for different distributors. In order to compensate for the attenuation, a passive power divider is made after adding an amplifier.
