Operational Description
RF Signal Processing System
The RF signal processing system consists fundamentally of three classical Wilkinson Splitter
elements that divide the RF signal from the antenna input evenly between four RF output ports.
There are several options that are available concerning the RF Signal Processing System.
These options are:
