About IXYSRF

IXYSRF was founded in 1987 as Directed Energy, Incorporated by George Krausse, Dave Adamson, and Ron Sherwood. The goal was simple; bring RF Power MOSFETs to the industry and provide uncompromising performance through our patented DE-Series low inductance, high speed, high power density package.

Designing the original DE-Series package to achieve the extreme performance improvements meant using our patented low inductance design along with BeO, Aluminum Nitride ceramic components along with other specialized materials.  As the technology became more widely accepted, we realized that many markets that were not currently using our device would benefit from the high performance of our package design but we would have to find a way to reduce the cost (and later remove BeO).

During this time, one of our best suppliers of silicon die was IXYS Corporation, whose die we used in many of the original DE-Series devices. We approached IXYS with a proposed partnership to reduce cost by taking our packaging concept to a more traditional semiconductor manufacturing process. After discussing the idea the IXYS management team responded with an offer to purchase Directed Energy and on May 16th, 2000 Directed Energy, became a wholly owned subsidiary of IXYS.

Now, as IXYSRF we continue to provide high-performance MOSFETs, Drivers and Integrated Modules using the DE-Series package. By working with the design team at IXYS we have developed die specifically for use in our DE-Series package and have leveraged the available of industry standard packaging to make our technology available to a wider array of applications and markets.

Here in our 5,400 square foot Colorado facility is focused on customer service, research and development and logistics.
