8 Way Power Divider

Looking into the Basics of the 8 Way Power Divider


When it comes to dividing input signals, power dividers are needed to accomplish the task. Power dividers are passive radiofrequency (RF) devices that does exactly that and produces two or more output frequencies only with a minimum amount of losses. These components are more commonly used in wireless systems to equally split the power across the circuitry.


In addition, the output frequency signals that are produced by the power dividers are generally of the same amplitude and phase. However, it depends entirely on the requirements these dividers have and they can vary both the amplitude and phase of the output signals. Moreover, there are a couple of different types of power dividers, one of which is the 8 way power divider.


As the name implies, the RF component splits input frequency into 8 different output signals. In order for one to understand the difference with power dividers that works 8 ways, below is the operational description of such.


The Operational Description Power Dividers that Work 8 Ways


The term “power divider” has been utilized in a lot of devices that’s meant to disseminate power to a lot of outputs, one could say that the term here has a limited sense when talking about it plainly. A single power divider has its own designated input and can have more than one output port. In addition, all ports are theoretically one and the same and the output ports are isolated from each other.


This is commonly the case with power dividers; however, it’s always not required for the transmission from the input port to be one and the same to every single output ports.

The Parameter Definitions of the Power Divider


Here are some of the important parameters of power dividers one must understand to better comprehend the functionalities of the power divider:


  • The Isolation: This pertains to the difference in dB of the frequency signal levels that’s estimated between the output ports with the input port that’s been properly eliminated.
  • The VSWR: This stands for the voltage standing wave ratio of the power divider. This is an estimate of the impedance deviation from the impedance trait of the said component.
  • The Amplitude Balance: This refers to the maximum peak-to-peak difference in the amplitude between the output ports of the power being split up over a particular frequency range.
  • The Phase Balance: Here, the maximum peak-to-peak difference in the phase (measured in degrees) between the output ports of the power divider over a particular band of frequency signals.
  • The Input Power: This refers to the maximum power that can be supplied to the input ports with every single output ports properly terminated.
  • The Insertion Loss: This pertains to the unrecoverable power that was lost along the process of dividing the input power and is based in dB on a single way transmission through the power divider.
  • The Power Ratings: All of the ratings experience are as a divider. The power rating of the device that utilizes it as a mixer are highly dependent on the input’s coherence.


These are just some of the specifications of the 8 way power divider. One must understand all of these to better comprehend how it functions in the wireless systems.
