The comprehensive platform features transmit and receive capabilities with high efficiency and output power, enabling reliable network connections while optimizing battery life — both critical for 5G applications.
In addition, the Sky5 Ultra leverages DSBGA packaging to reduce the footprint and advanced TC-SAW and BAW filtering to provide 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 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.
“With industry momentum accelerating towards 5G, Skyworks is leading the way with the technological innovations and systems expertise demonstrated by our Sky5 portfolio, a highly flexible and customizable suite designed to meet customers’ global requirements,” said Joel King, senior vice president and general manager of Mobile Solutions at Skyworks.
“Sky5 Ultra represents another breakthrough in simplifying the growing complexity of 5G device development — delivering unmatched performance while expediting deployment through full integration and optimized form factors. We are empowering top mobile device manufacturers and network providers with complete, turnkey solutions that will ultimately bring 5G to realization,” King said.
