SKY77619-51中文资料SkyHi™ Multimode Multiband Power Amplifier Module for Quad-Band GSM/EDGE / Penta-Band (I, II, III/IV, V, VIII) WCDMA / CDMA / HSDPA / HSUPA / HSPA+ / LTE数据手册Skyworks规格书

描述 Description

Please note: SKY77619-51 is being discontinued and is not recommended for new designs. The suggested replacement is SKY77927-21 The SKY77619-51 SkyHi™ Power Amplifier Module (PAM) is a hybrid, multimode multiband (MMMB) module that supports 2.5G and 3G/4G handsets and operates efficiently in GSM, EGPRS, EDGE, WCDMA, CDMA, and LTE modes. The PAM consists of: a GSM 800 / EGSM 900 PA block, a DCS1800 / PCS1900 PA block, separate WCDMA blocks operating in 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 \u001E 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 SKY77619-51 uses a new compact architecture supporting the GSM850, EGSM900, DCS1800 and PCS1900 bands. The PAM also supports 2.5G Class 12 Enhanced General Packet Radio Service (EGPRS) multi-slot operation and EDGE linear modulation.

WCDMA: The SKY77619-51 uses an enhanced architecture to support WCDMA / CDMA High-Speed Downlink Packet Access (HSDPA), High-Speed Uplink Packet Access (HSUPA), and LTE modulations; cover multiple bands for 3GPP, including bands I, II, III/IV, V, and VIII; and operate at different power modes. The module is fully controllable via four logic lines and band-enable interfaces.

LTE: The SKY77619-51 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
