Skyworks Launches Breakthrough Front-End Solutions for 5G

At Mobile World Congress in Barcelona, Skyworks has launched the Sky5 Ultra platform. Leveraging decades of systems expertise, Skyworks has developed a fully integrated, baseband agnostic solution that combines all of the critical front-end functionality required to enable high performance 5G mobile devices with global coverage in an exceptionally compact form factor. The Sky5 Ultra platform features best-in-class transmit and receive capabilities with unprecedented efficiency and output power, enabling highly reliable network connections while optimizing battery life - both critical for 5G applications. In addition, the Sky5 Ultra leverages DSBGA packaging, dramatically reducing the footprint, and advanced TC-SAW and BAW filtering, uniquely providing the best performance at each targeted frequency band. The solution also supports up to 100 MHz wide bandwidth, maximizing data throughput at ultra-fast speeds.

5G rollouts have already begun and will continue to ramp up over the next few years. According to the Global Mobile Suppliers Association, 11 worldwide operators have announced limited 5G service launches and seven additional operators have turned on 5G base stations, with commercial services to follow.

Sky5 Ultra incorporates Skyworks’ high-efficiency transmit, diversity receive (DRx) and MIMO modules with industry-leading noise figure and low insertion loss, in addition to an array of aperture tuners and antenna swap switches for optimal antenna management. Like all Sky5 solutions, the comprehensive front-end platform supports new 5G NR waveforms and spectrum in addition to enhanced carrier aggregation and 4G/5G dual connectivity, while delivering exceptional levels of integration and performance.
