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 are internally matched to 50 Ω to minimize the number of 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 SKY78011-21 uses a new compact architecture supporting the GSM850, EGSM900, DCS1800 and PCS1900 bands. The FEM also supports 2.5G Class 12 Enhanced General Packet Radio Service (EGPRS) multi-slot operation and EDGE linear modulation. WCDMA: The SKY78011-21 uses an enhanced architecture to: support WCDMA/High-Speed Downlink Packet Access (HSDPA) and High-Speed Uplink Packet Access (HSUPA) modulations; cover multiple bands for 3GPP, including bands I, II, III, V, and VIII; operate at different power modes. The module is fully controllable via four logic lines and band-enable interfaces. LTE: The SKY78011-21 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. Receiver Section: The SKY78011-21 has integrated Duplexers, RX SAWs and SP12T SOI switch to provide 2G / 3G / 4G Rx paths from antenna to LNA port of RFIC. Optimized “Rx paths and matching circuits” with well-grounded guard trace (high Tx–Rx isolation) inside module mitigate de-sense problem and enhance sensitivity performance. TRx Port: The SKY78011-21 provides three vacant broadband TRx ports for additional band requirements. |
