SKY78131-13

SKY78131 SkyOne® Ultra 3.0 Front-End Module for WCDMA / LTE Bands 1, 2, 3, 4, 25, 34, 39

Please note: SKY78131-13 is being discontinued and is not recommended for new designs. The suggested replacement is SKY58109-51

The SKY78131 SkyOne® Ultra 3.0 is a multimode multiband (MMMB) Front-End Module (FEM) that supports 3G/4G, and CDMA handsets and operates efficiently in CDMA, TD-SCDMA, WCDMA, HSPA, and LTE modes. The FEM consists of a WCDMA blocks operating in the middle bands, a logic control block for multiple power control levels, and band enable functions in both cellular and UMTS. 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.

WCDMA: The SKY78131 enhanced architecture supports WCDMA/High Speed Downlink Packet Access (HSDPA) and High Speed Uplink Packet Access (HSUPA) modulations, covers multiple bands for 3GPP including bands 1, 2, 4 and operates at different power modes. The module is fully controllable via a MIPI serial interface.

LTE: The SKY78131 meets spectral linearity requirements of LTE modulation with QPSK/16QAM up to 20 MHz bandwidth, including various resource block allocations, with excellent power-added efficiency.

CDMA: The SKY78131 meets spectral linearity requirements of CDMA2000 and EVDO Release A modulation with good power-added efficiency.

TD-SCDMA: The SKY78131 meets spectral linearity requirements of TD-SCDMA modulation dedicated transmit output port.

Receiver Section: The SKY78131’s integrated Duplexers, RX SAWs, LNA and an Antenna switch support simultaneous Downlink Carrier Aggregation for additional Rx data rate and provides 3G/4G Rx paths from antenna to input ports of RFIC. Carrier Aggregation (CA) 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 module mitigate desense problems and enhance sensitivity performance.

LNA Rx Ports: The SKY78131 provides three LNA ports to support 4x4 MIMO.

TRx and Rx Ports: The SKY78131 provides six TRx ports.
