RF Power Splitter Concept to Completion (035)

In this video I walk through the process of developing an R.F. Power Splitter. I start with the basic concept and an ugly bench experiment and work through to a totally awesome implementation showing the process along the way. I provide the complete design of the final project in a ZIP file (see below) so you can simply download it and do it yourself. While my example is that of a 3 port, 50 Ohm device, what you learn here will equip you to build a splitter with as many ports and with whatever characteristic impedance you need.
