The RFFE v1.10 specification defines a standardized control architecture for RF front-end devices and offers a low-complexity solution for multimode, multiband, and multi-antenna configurations. Both specifications expand upon previous versions by addressing today's complex multi-radio wireless systems.


Flexible and efficient, the DigRF v4 interface supports next-generation technologies including HSPA+, LTE, Mobile WiMAX, and 3GPP standards encompassing 2.5G and 3.5G. High data rates and scalability also enable coverage of other non-3GPP air interfaces. DigRF v4 leverages high-speed serial technology and offers optimized power efficiency through multi-speed modes and rapid cycling between active and power-saving operation.
