Background

The power divider is also called a power divider, and is a device that divides one path of input signal energy into two or more paths of energy with equal or unequal outputs, or conversely combines the multiple paths of signal energy into one path of output, and at this time, may be called a combiner. Certain isolation degree should be guaranteed between output ports of one power divider. The over-current distributor is divided into an active type and a passive type, one path of signal can be evenly distributed to be changed into a plurality of paths of output, generally, each path has attenuation of several dB, the signal frequency is different, the different attenuation of the distributor is also different, and in order to compensate the attenuation, the passive power distributor is made after an amplifier is added.
