Skyworks released a set of antenna switch solutions supporting LTE, LTE-Advanced and next-generation carrier aggregation architectures at the Mobile World Congress in Barcelona, Spain. The portfolio includes highly integrated antenna switch modules (ASM) as well as transmit and receive diversity switches. The dual-mode MIPI® RFFE-compliant modules are modem agnostic, making them compatible with every leading chipset provider.
Carrier aggregation allows mobile service providers to combine spectrum and increase data rate throughput by utilizing two or more bands simultaneously instead of the single band method used currently, thereby providing consumers an enriched data experience regardless of location. OEMs can quickly modify their RF front-ends and adapt to multiple band configurations, providing a high level of design flexibility to support differing regional band requirements.
Antenna Switch Portfolio Supporting LTE, LTE Advanced and Carrier Aggregation
Designed specifically for carrier aggregation, the SKY13530 (dual-pole-ten-throw), SKY13532 (dual-pole-14-throw) and SKY13535 (dual-pole-21-throw) ASM portfolio have independent programmable registers for low band and mid-high band switch banks, allowing for multiple carrier aggregation band combinations. This flexibility provides rapid regional customization for smartphone and modem manufacturers. In addition, the low band switch banks are optimized for improved harmonic suppression.
Designed for Skyworks’ carrier aggregation LTE portfolio, the SKY13491-21 (single-pole-fourteen-throw), SKY13492 (single-pole-sixteen-throw), SKY13488 (single-pole-twelve-throw) and SKY13498 (single-pole-ten-throw) provide scalability in non-carrier aggregation SKUs.
Both carrier aggregation and non-carrier aggregation antenna switches feature an integrated dual mode MIPI® RFFE controller. Common truth tables and common footprint philosophy allow for system scalability and programming code reuse to expedite front-end modifications.
