Qualcomm JV to Spark Mobile Industry Path Towards RFFE Integration
As the mobile communications industry moves fast toward higher speed, low latency, and ultra-reliable connections, new technologies are emerging as fundamental building blocks for enabling networks, commonly called LTE Advanced and LTE Advanced Pro. The addition of multiple carrier aggregation (CA) at both the downlink and uplink levels, MIMO, antenna tuning, and envelope tracking brings with it antenna diversity, which means that the RF system must accommodate an increasing number of front-end components. LTE spectrum fragmentation is putting even more constraints on the RF real estate. If the industry does not act quickly and provide some much-needed rationalization and integration at the RF front end (RFFE), then it faces some serious challenges over the coming years.
