Introduction

Skyworks SKY77643-61 SkyLiTE™ is a multimode multiband (MMMB) Power Amplifier Module (PAM) that supports 3G / 4G handsets and operates efficiently in CDMA, WCDMA, TD-SCDMA, and LTE modes. The module is fully programmable through a Mobile 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/output ports internally matched to 50 Ω (reduces the number of external components). A CMOS integrated circuit provides the internal MFC interface and operation using standard MIPI controls. Extremely low leakage current maximizes handset standby time. The InGaP die and the silicon die and passive components are mounted on a multi-layer laminate substrate. The assembly is encapsulated in a 4.0 mm × 6.8 mm × 0.71 mm, 42-pad MCM, SMT package which allows for a highly manufactural, low cost solution. 3G: The SKY77643-61 supports CDMA, WCDMA, High-Speed Downlink Packet Access (HSDPA), High Speed Uplink Packet Access (HSUPA), High Speed Packet Access (HSPA+), and TDSCDMA modulations. Varying the input power level provides output power control. VCC is adjusted using a DCDC converter to maximize efficiency for each power level and modulation type. 4G: The SKY77643-61 supports 1.4, 3, 5, 10, 15, 20 MHz channel bandwidths. Similar to 3G operation, output power is controlled by varying the input power and VCC is adjusted using a DCDC converter to maximize efficiency for each power level. Supports LTE Power Class 2 HPUE operation. 3G / 4G Modulation scheme includes:

• WCDMA Voice Release 99
• HSDPA categories
• HSUPA
• HSPA+
• TD-SCDMA
• CDMA2000 1xRC1, 1xRC3
• CDMA2000 EVDO
• LTE 1.4, 3, 5, 10, 15, 20 MHz Channel BW
• TDD LTE
• Uplink Carrier Aggregation (CA) support for Band 39 (35 MHz) and Bands 40/41 (40 MHz)

Features

• LTE Power Class 2 High Power User Equipment (HPUE) operation
• Two T/R (RX) ports and 14 outputs
• Industry-leading PAE for 3G/4G
