Featured: AX-RadioLab

radiolab-So much smarter than just a register value configurator.


The AX-RadioLab is a GUI code generator that creates not only all register settings required for a specific AX8052F143/AX5043 or AX8052F151/AX5051 based radio link, but also a complete C code firmware stack which is compiled, down-loaded to hardware and run.

  • Create an application software which is compatible with your existing protocols in minutes
  • Have the ease of use of a module with a chip solution
  • Be totally flexible instead of forced into a given protocol structure


What can AX-RadioLab do for you?

  • AX-RadioLab creates your radio application firmware stack
  • AX-RadioLab creates test code for CW, random data or pattern
  • AX-RadioLab produces power optimized code
  • AX-RadioLab enables immediate BER and PER testing
  • AX-RadioLab can sniff the radio channel



  • AX-RadioLab supports synchronous and asynchronous protocols w/ or w/o acknowledge
  • AX-RadioLab has a GUI driven packet creation
  • AX-RadioLab creates SW stacks compatible with many existing standards and HW platforms
  • AX-RadioLab has a Software PLL to keep synchronous timing
  • AX-RadioLab uses the AXRadio API as foundation for code



  • A SW without API is like a house without foundation. AXSEM SW is built on the AXRadio API.
  • AXRadio API A clean way how your software can speak to our radios
  • AXRadio API is a library/driver for AXSEM radio chips
  • Timed code supports sleep and deep sleep
  • Multiple channels, multiple frequencies
