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.
