Since its release in July 2010, the MIPI RFFE℠ specification has evolved as the de-facto multi-drop bus architecture to control RF Front-End components. Over the past decade, its constant evolution has ensured absolute adherence to real-time performance of the RF-Front-End in terms of the critical control timing budget. As the latest cellular technology (5G) takes the RF-Front-End to a whole new level of complexity, the recently released MIPI RFFE v3.0 is geared toward meeting these new challenges.
This session presents the new features of MIPI RFFE v3.0 from a system-architecture perspective to help architecture and design engineers understand how the triggering features in the latest version work together to improve performance and to switch quickly among the various bands and band combinations in a 5G system:
- Timed triggers that allow for tighter, synchronized timing control of multiple carrier aggregation configurations
- Mappable triggers that enable groups of control functions to be remapped
- Extended triggers that boost the number of unique triggers available in the RF control system and accommodate increasingly complex radio architectures
