Who are we?  

Well, we are really just me, Rick Raffanti, aerospace electronic engineer for a few decades now.  I'm nominally a one-man shop, but I usually collaborate with scientists and other engineers, and over the years I've established and maintained relationships with trusted technical professionals to do specialized tasks, such as PCB design, electronic assembly, and software development.

                   








           See Publications >











Here's what I do:
  • Analog design, DC to a few GHz
  • Low noise design
  • Data conversion (analog/digital and digital/analog), in the GSPS range.
  • Large FPGA (Virtex 7) system design, including firmware and embedded processors
  • Complete system design, hardware including the above, with an API interface.
  • Aerospace designs.  I was employed at UC Berkeley's Space Sciences Lab for 14 years and was responsible for many space-flight systems.
  • Careful documentation
