Resistive Power Signal Tap Designer
aka RF Sampler, Resistive Unequal Power Divider
Notes
This Calculator was inspired by the article "Designing Resistive Unequal Power Dividers"
by Greg Adams, published in High Frequency Electronics, March 2007.
The formulas have been derived by starting with a Resistive Power Split and then replacing one branch with a Power Splitter to create a Tap.
