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...

FUTURE TECHNOLOGY & GROWTH OPPORTUNITIES

As a foremost authority in attenuation and switching technologies, JFW Industries continues to advance its baseline products and services. Each year, we create hundreds of new models at the request of our customers. These innovations range from the expanded performance of existing items to the inception of entirely new product lines. It is this constant state of research and development that allows JFW to provide customized RF components and systems without the outrageous prices usually associated with these services. Some of our recent progresses include:

  • New 3 GHz, 0-127 dB Programmable Attenuator
  • Complete Line of 20-4300 MHz Solid-State Switches
  • Solid-State, 100 Watt "Hot Switch"
  • Line of Specialized Directional Couplers
  • Many Components Now to 6 GHz
  • More 75-Ohm Components

One line of products that has seen tremendous growth in recent years is our family of automated RF test systems. These systems include a multitude of functionality, but are often based upon a multiple-path attenuation system or a switch matrix. We expect the need for such systems to continue to grow in the years to come.
