描述 Description

Skyworks SKY77643-81 SkyLiTE™ is a multimode multiband(MMMB) Power Amplifier Module (PAM) that supports 3G / 4Ghandsets and operates efficiently in CDMA, WCDMA, TD-SCDMA,and LTE modes. The module is fully programmable through aMobile Industry Processor Interface (MIPI®).The PAM consists of a WCDMA / LTE block for low, high, and midbands,a Multi-Function Control (MFC) block, and RF input/outputports internally matched to 50 Ω (reduces the number of externalcomponents). A CMOS integrated circuit provides the internal MFCinterface and operation using standard MIPI controls. Extremelylow leakage current maximizes handset standby time.The InGaP die and the silicon die and passive components aremounted on a multi-layer laminate substrate. The assembly isencapsulated in a 4.0 mm x 6.8 mm x 0.75 mm, 42-pad MCM,SMT package which allows for a highly manufacturable, low costsolution.3G: The SKY77643-81 supports CDMA, WCDMA, High-SpeedDownlink Packet Access (HSDPA), High Speed Uplink PacketAccess (HSUPA), High Speed Packet Access (HSPA+), and TDSCDMAmodulations. Varying the input power level providesoutput power control. VCC is adjusted using a DCDC converter tomaximize efficiency for each power level and modulation type.4G: The SKY77643-81 supports 1.4, 3, 5, 10, 15, 20 MHzchannel bandwidths. Similar to 3G operation, output power iscontrolled by varying the input power and VCC is adjusted using aDCDC converter to maximize efficiency for each power level.Supports LTE Power Class 2 HPUE operation.3G / 4G Modulation scheme includes:WCDMA Voice Release 99HSDPA categoriesHSUPAHSPA+TD-SCDMACDMA2000 1xRC1, 1xRC3CDMA2000 EVDOLTE 1.4, 3, 5, 10, 15, 20 MHz Channel BWTDD LTEUplink Carrier Aggregation (CA) support for Band 39 (35 up to MHz), Bands 1, 2/25, 3, 4, 7, 38, 40, 41 (up to 40 MHz)
