Device Overview

General Description

3-Way Wilkinson power dividers can be used for both in-phase power splitting and power combining applications. These power dividers feature the lowest insertion loss (ideally 4.77 dB 3-way splitting loss), excellent amplitude and phase balance, and high isolation across the entire operating band.
