clicking around the
Matrix website the other day, I happened upon a nice set of online
calculators like the
cascade calculator shown in the thumbnail. Also included under the
"RF Design Tools" menu are Tee & Pi Attenuator Calculator, VSWR
Mismatch & Power Uncertainty, Microstrip Line Design, Power Dividers
/ Couplers Designer, and a few other calculators. A nice feature about
these calculators are the sliders and dials for making parameter adjustments,
or you can enter an exact number. Many of the RF / microwave vendor
websites have nice calculators buried in them.
Below are a few
examples of the Phase Matrix calculators.
