One of the critical enabling technologies of LTE is Carrier Aggregation. Simply stated, Carrier Aggregation (CA) combines two or more channels (also called carriers) of available wireless spectrum to greatly increase data rates to and from an LTE smartphone. CA effectively doubles smartphone data rates and allows for more efficient use of available network capacity. It combines multiple channels in both high and lower frequency bands, or adjoining channels within the same frequency band to deliver the higher data throughput specified in both FDD and TDD LTE standards.
A welcome addition for LTE customers, CA is considered the first step in LTE Advanced commercialization. CA can also provide increased user data rates for users that can be traded off to maximize capacity for certain applications.
RFMD helps smartphone OEMs and network providers with the high-performance components needed to implement Carrier Aggregation. We understand the unique RF linearity and isolation requirements of CA and have a broad array of components optimized for CA performance in mobile devices.
RFMD’s different types of carrier aggregation solutions includes:
Our portfolio also provides other components that offer the size and performance needed for new CA-enabled mobile devices.
