RF Cafe began life in 1996 as "RF Tools" in an AOL screen name web space totaling 2 MB. Its primary purpose was to provide me with ready access to commonly needed formulas and reference material while performing my work as an RF system and circuit design engineer. The World Wide Web (Internet) was largely an unknown entity at the time and bandwidth was a scarce commodity. Dial-up modems blazed along at 14.4 kbps while typing up your telephone line, and a nice lady's voice announced "You've Got Mail" when a new message arrived...

Please click here to visit U.S. MicrowavesUS Microwaves capabilities encompass circuit / layout design, process design/simulations, mask manufacturing, substrate laser machining, sputtering depositions, patterning, electroplating, etching, PECVD dielectric depositions, vacuum and controlled atmosphere annealing, dicing, E-test, visual inspections, die attach, wire bonding, waffle packing, custom housings, etc.

The wafer fabrication plant is located in Santa Clara, California. All critical wafer fabrication steps are conducted in a class 10 environment to ensure highest yields and reliability of our products.

US Microwaves starts production cycles for microwave thin film circuits with sophisticated layout design tools and experienced design engineers that convert customers requirements in data that is fed to the mask shop operation. In the mask shop, 10x and 4x steppers are used for generating high quality chrome masks.

Typical turn around for the masks is 24 hours from receipt of customer data. Ceramic substrates are coated via sputter deposition and further processed through photolithography, electroplating, plasma etching, annealing, dicing, e-testing, visual inspection, waffle packaging.
