SKY77646

Multimode Multiband Power Amplifier Module for Quad-Band GSM/EDGE – Bands (1, 25, 3, 4, 26, 8, 13, 12, 20, 28, 34, and 39) WCDMA / HSDPA / HSUPA / HSPA+ / LTE

The SKY77646 hybrid, multimode multiband (MMMB) Power Amplifier Module (PAM) supports 2.5G and 3G/4G handsets and operates efficiently in GSM, EDGE (EGPRS), CDMA, WCDMA, TD-SCDMA, and LTE modes. The PAM consists of a GSM800/EGSM 900 PA block, a DCS1800/PCS1900 PA block, separate WCDMA/LTE blocks operating in low and mid 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  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 new compact architecture of the SKY77646 supports the GSM850, EGSM900, DCS1800, and PCS1900 bands, 2.5G Class 12 Enhanced General Packet Radio Service (EGPRS) multi-slot operation, and EDGE linear modulation.

WCDMA: The enhanced SKY77646 architecture supports WCDMA, High-Speed Downlink Packet Access (HSDPA), High-Speed Uplink Packet Access (HSUPA), and LTE modulations. It also covers multiple bands for 3GPP including bands 1, 25, 4, 26, and 8; operates at different power modes. The module is fully controllable via MIPI interface.

TD-SCDMA/TDD-LTE: The enhanced SKY77646 architecture supports TD-SCDMA bands 34/39 and TDD-LTE band 39 through ET or APT modes.

LTE: The SKY77646 meets the spectral linearity requirements of LTE modulation with QPSK/16QAM up to 20 MHz bandwidth, including various resource block allocations, with good power-added efficiency
