Power Divider/Combiner

Example schematic of 4Way resistive and 4Way reactive power dividers

A power divider/combiner is a device used to route signals. It is available with either resistive or reactive design.  Resistive power dividers are constructed in a star configuration which functions like a RF hub which is ideal in radio-to-radio RF testing.  Radios connected to the RF hub will all Rx each other at the same signal level.  Reactive power dividers have a fan-in/fan-out layout.  Reactive power dividers have less through loss than their resistive counterparts.  The reactive design also has isolation (20dB typical) between the combiner ports.
