The SKY78130 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, WCDMA, HSPA, and LTE modes. 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 SKY78130 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 5, 8 and operates at different power modes. The module is fully controllable via a MIPI serial interface.
LTE: The SKY78130 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 SKY78130 meets spectral linearity requirements of CDMA2000 and EVDO Release A modulation with good power-added efficiency.
Receiver Section: The SKY78130’s integrated Duplexers, RX SAWs, LNA and an Antenna switch support simultaneous Downlink Carrier Aggregation for additional Rx data rate 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 SKY78130 provides two LNA input ports to support additional bands.
TRx and Rx Ports: The SKY78130 provides three TRx ports.
PA AUX Ports: The SKY78130 provides two PA AUX output ports.
