MIPI Radio Front-End
RFFE - Arasan Chip Systems, Inc. (Arasan)
Mobile phone radios have developed into highly complex, multi-band and multi-standard designs that often have multiple radio frequency (RF) signal chains. The MIPI Alliance Specification for RF Front-End Control Interface (RFFE) was developed to offer a common and widespread method for controlling RF front-end devices. The RFFE Master IP core typically resides in the RFIC in a mobile platform, and utilizes the RFFE bus to identify, program and monitor the registers in RF front end Slave devices through programmed IO. It is designed to support existing standards such as LTE, UMTS, HSPA and EGPRS, and is usable in configurations ranging from single Master/single Slave to multi-Master/multi-Slave.
