SKY78117-14A中文资料SkyOne® Ultra 2.0 Front-End Module for FDD/TDD LTE Bands 7, 30, 38, 40, 41数据手册Skyworks规格书

描述 Description

Please note: SKY78117-14A is being discontinued and is not recommended for new designs. The SKY78117-14A SkyOne® Ultra 2.0 is a multimode multiband (MMMB) Front-End Module (FEM) that supports 4G handsets and operates efficiently in FDD/TDD LTE modes. The FEM consists of an LTE block operating in the high bands, a logic control block for multiple power control levels. RF I/O ports internally matched to 50 ohms minimize the need for external components. Extremely low leakage current maximizes handset standby time. The InGaP/GaAs die and passive components are mounted on a multi-layer laminate substrate and the assembly encapsulated in plastic overmold.

LTE: The SKY78117-14A meets spectral linearity requirements of LTE modulation with QPSK/16QAM up to 40 MHz bandwidth in Bands 38, 40, and 41 including various resource block allocations, with good power-added efficiency.

Receiver Section: The SKY78117-14A integrated Duplexers support Downlink Carrier Aggregation (CA) for additional Rx data rate and provide 4G Rx paths from antenna to LNA port of RFIC. Carrier Aggregation requirements for noise and harmonics are designed-in for best desense performance. Optimized low insertion-loss Rx paths, matching circuits, and well-grounded guard traces (high Tx–Rx isolation) inside the module mitigate desense problems and enhance sensitivity performance. An integrated RX consolidated switch provides the ability to match different RX port mapping on different platforms.

TRx and Rx Ports: The SKY78117-14A provides three Tx ports and one Antenna port (Band 7).
