Characteristics of Resistive Power Divider/Combiner

- Resistive power dividers/combiners function all the way down to DC.

- Resistive Power dividers/combiners can be used to combine several signals or split a single signal.

- Due to their symmetric design, the isolation of a resistive divider/combiner is equal to it's insertion loss.
Example: A 2way resistive power divider/combiner has 6dB of insertion from any port to any other port. All paths have 6dB of insertion loss.

- Becuase a resistive Power divider/combiner has identical insertion loss from any port to any other port, it acts much like a node in a mesh network.

- A resistive power divider/combiner has much higher insertion loss than reactive power divider/combiner. Example: 2-way resistive = 6dB, 2-way reactive = 3dB

- Some configurations such as 5-way, 7-way, and 10-way are more readily available as resistive power dividers/combiners than as reactive power dividers/combiners.
