SKY78026

SkyOne™ Multimode Multiband Tx Front-end Module for Quad-Band GSM / GPRS / EDGE WCDMA / HSPA / HSPA+ / LTE / CDMA

The SKY78026 SkyOne™ Multimode Multiband (MMMB) Front-End Module (FEM) supports 2.5G, 3G/4G, TDD-LTE, and CDMA handsets and operates efficiently in GSM, GPRS, EDGE, WCDMA, HSPA, TDD-LTE, and LTE modes. The FEM consists of a GSM800/EGSM900 PA block, a DCS1800/PCS1900 PA block, separate WCDMA blocks operating in the low and high 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.

GSM / EDGE: The SKY78026 with new compact architecture, supports the GSM850, EGSM900, DCS1800 and PCS1900 bands, as well as 2.5G Class 12 Enhanced General Packet Radio Service (EGPRS) multi-slot operation and EDGE linear modulation.

WCDMA: The SKY78026’s 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 I, II, III, IV, V, and VIII, and operates at different power modes. The module is fully controllable via a MiPi serial interface.

LTE: The SKY78026 meets spectral linearity requirements of LTE modulation with QPSK/16QAM up to 20 MHz bandwidth, including various resource block allocations, with good power-added efficiency.

CDMA: The SKY78026 meets spectral linearity requirements of CDMA 2K and EVDO Release A modulation with good power-added efficiency.

Receiver Section: The integrated Duplexers, RX SAWs, and SP16T SOI switch of the SKY78026 provide 2G/3G/4G Rx paths from antenna to LNA port of RFIC. Additionally, GPS and LB/HB WiFi coexistence are designed-in for exceptional support to maintain all radio performance, even in user scenarios of simultaneous use. Optimized low insertion-loss Rx paths, matching circuits, and well-grounded guard traces (high Tx–Rx isolation) inside the module mitigate de-sense problems and enhance sensitivity performance.

TRx and RX Ports: The SKY78026 provides eight auxiliary ports.
