Since its introduction in 2010, MIPI RFFE has become the de facto RF front-end control interface in virtually every device with cellular connectivity. But the recent rollout of 5G has presented new challenges for device designers and OEMs—the number of RF bands for uplink and downlink communications has increased significantly—while at the same time, the subcarrier spacing windows have further narrowed.
In this webinar, find out how the new version of MIPI RFFE (v3.0) addresses these challenges with new triggering features designed to deliver tighter precision and reduced latencies in the control of RFFE subsystems. You’ll also learn how these various types of triggers 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
The MIPI RFFE Working Group chair and vice chairs also share their efforts to gather requirements for Frequency Range 2 (FR2) for development of the next evolution of the specification.
