MIPI RFFE offers a common and widespread method for controlling RF front-end devices. RFFE provides a low-complexity solution to meet the cost and performance targets of RF front-end components, and provides a common communication link for components. It offers extensibility from simple configurations with one Slave on a single bus, all the way to complex configurations with many Slaves on a single bus, or perhaps distributed on multiple buses.
RFFE has been very widely adopted, and is deployed in billions of devices. With RFFE v2.0 many new features have been added including: support for multiple devices controlling the bus, support for interrupts, additional bus operating frequencies, additional read back methods, and additional reserved registers for unified control methods. All of this has been added whilst also retaining backwards-compatibility with capable devices.
Many companies from across the RF Front End ecosystem providing many products—including Power Amplifiers (PAs), Low-Noise Amplifiers (LNAs), filters, switches, power management modules, antenna tuners and sensors—took part in developing MIPI RFFE. In December 2014, RFFE v2.0 was adopted by the MIPI Alliance.
This webinar outlines the key features, implementation benefits, and future advancement of MIPI RFFE.
Jim Ross Jim Ross is a Technical Director with Skyworks Solutions and has 20+ years of digital design experience throughout his career which has mainly been focused in developing devices in the mobile platform ecosystem. Jim has chaired the MIPI RFFE working group since 2011 and previously was the vice chair since the working groups’ inception in 2008. He has his BS and his MS in Electrical Engineering from the University of North Dakota.
John Oakley John Oakley has nearly 20 years of successful digital design experience at Motorola, Freescale, Fujitsu, and Intel and has developed over 50 successful integrated devices. John’s willingness to help and mentor, in addition to his deep technical expertise, make him key member of Intel’s technical team. He is a contributor to 3GPP standards and their application to real world devices, and he is currently Vice Chairman of the MIPI working group RFFE. John received his BS in Electrical Engineering from Texas A&M University.
Beyond the work environment, John is a Gold Life Master at Bridge. He has been a Boy Scout leader and has a collection of 50+ swords. He is the 12th man on the Texas A&M football squad, and (perhaps most impressive) he manages to keep his wife and his boss happy
