Qorvo: RF architecture choices for next-generation handset designs

January 18, 2017 // By Ben Thomas, Bryan Soukup
The smartphone market has diversified into multiple segments with differing design goals and priorities, which require different approaches to RF front end (RFFE) integration. Flagship phones are premium devices designed for super-regional or global use. They require a highly integrated RFFE architecture that integrates all major transmit and receive functionality, including support for all major frequency bands and global carrier aggregation deployments. For mid-tier regional handsets manufacturers seek to minimize handset cost by including only the RF components needed for specific regional bands, yet they need to rapidly adapt handset designs for different regions and customers. This requires an RFFE architecture that enables design flexibility allowing manufacturers to produce models for specific regions and operators by adding appropriate filters.
