RF System Design Accelerators: Hardware Development Tools to Speed Time-to-Market and Reduce Risk

RF and radio system development is becoming more complex at a time that technical support is becoming more diffused. Design Accelerator hardware development tools can speed design and development. This paper presents how Design Accelerators reduce design time, an analysis of how different types of accelerator boards serve different development needs (from designing waveforms or developing software, to proving concepts and prototyping), as well as an exploration of the different levels of integration available in accelerator boards.
