RF Cafe has ended the dearth of T-shirts, sweatshirts, coffee mugs, and other
items that sport engineering themes. Our newest design sports the thesis, "RF
Engineers...We Are the World's Match Makers," with colorful, instructional
Smith Chart™ designs and VSWR-Return Loss-Reflection Coefficient conversion formulas.
I really want these items to be "out there," so the new prices are set at cost
+ 50¢. Click Here
This design is sure to be popular with RF Cafe visitors, and will be added to
the potential prizes for our monthly drawing of a name of someone who purchases
RF Cafe software. Items that qualify
for the RF Cafe T-shirt Contest are colored in GREEN.

RF Engineers - We are the World's Match Makers™
This custom design by RF Cafe is a montage of Smith Charts with forbidden regions
and their associated L-C networks, along with conversions between return loss, reflection
coefficient, and VSWR.
