Standard power divider terminology says that an X-way power divider can divide your input signal into X copies. So, a 3-way divider has 1 input and 3 outputs for a total of 4 connectors.

2) How much isolation does a resistive power divider have?

Due to their symmetric design, the isolation of a resistive power divider is equal to its insertion loss. The insertion loss between any of the ports is equal. Example: A 2-way resistive power divider/combiner has 6dB of insertion loss from port to port.

3) Should I use a resistive or reactive power divider/combiner?

Reactive power divider/combiners have lower insertion loss and better isolation than resistive power divider/combiners. If your frequency range allows you to use a reactive power divider/combiner, then JFW recommends this option.

4) I need a custom power divider/combiner designed. How much are your typical NREs (non-recurring engineering change)?

JFW does not charge NREs. Please send you custom requirement to sales@jfwindustries.com.

5) What are the pros and cons of reactive power divider/combiners versus resistive power divider/combiners?

Reactive Pros	Resistive Pros
High isolation	Wide frequency band (and works at DC)
Low insertion loss	High power capabilities
Reactive Cons	Resistive Cons
Narrow frequency band	High insertion loss
Lower power	Low isolation
