The CafePress store is now closed.
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 +$2.

These custom designs appear on my products. If there is a particular item offered by products that you would like us to add one of these designs to, please send an e-mail and let us know.
RF Engineers - We are the World's Match Makers™
