Originally released in July 2010, the MIPI RF Front End Control Interface, MIPI RFFESM, is the world’s de facto standard interface for control of radio frequency (RF) front-end (FE) subsystems. It delivers fast, agile, semi-automated and comprehensive control of the complex RF subsystem environment, which has rigorous performance requirements and can include up to 19 components per bus instance (up to 15 subordinate devices and up to four main devices), including power amplifiers, LNAs, antenna tuners, filters and switches.
The interface can be applied to the full range of RF front-end components to simplify product design, configuration and integration, and to facilitate interoperability of components supplied by different vendors. The conveniences make it easier for RF device vendors, baseband and transceiver vendors and mobile OEMs to address end-user needs for faster data speeds and better call quality and to develop scalable solutions and expedite time to market for new designs in the mobile, automotive, industrial and Internet of Things (IoT) sectors.
MIPI RFFE is developed by the MIPI RF Front-End Control Working Group. The current release, v3.1, was released in 2023.
The specification is available only to MIPI Alliance members. For information about joining MIPI Alliance, visit Join MIPI.
