Carrier Aggregation: Status of Devices, Operators and Bands

Please contact us to discuss pricing Contact Us

Report Summary:

Carrier aggregation shipped in more than 77 LTE-A mobile device models last year, and will ship in a growing proportion devices in the future, employing more bands in both the downlink and uplink directions. This will have a profound effect on RF front-end architectures in cellular devices, leading to more highly integrated front-ends and increased demand for antenna tuners, LNAs, RF switches, filters, envelope tracking and new forms of PAs.
