Wilkinson Power Dividers and Feed Networks – A Brief Overview By Greg Alton via Knowles Precision Devices  The Wilkinson Power Divider, designed by Ernest Wilkinson in the 1960s, uses quarter wave transformers to split an input signal into two equal phase output signals. Since the design is reciprocal, Wilkinson Power Dividers can also be used...

Power Divider Basics By Peter Matthews via Knowles Precision Devices  Radio frequency (RF) power dividers are designed to split an incoming signal into multiple outputs such that there’s a portion of the original signal’s power in each output. Given their critical function, power dividers play a particularly important role in antenna systems, telecommunications, and signal...
