SKY77643-21
SkyLiTE™ Multimode Multiband Power Amplifier Module

SkyLiTE™ is Skyworks' newest family of LTE devices which consists of highly integrated modules incorporating the amplification, switching, WiFi filtering and coupler functions required to support all major FDD/TDD bands. With the addition of external duplexers, this product family provides OEMs with a scalable and reconfigurable front-end system suitable for markets worldwide.

SKY77643 SkyLiTE™ is a key building block for global or five-mode front-end implementation. As a hybrid multimode multiband (MMMB) Power Amplifier Module (PAM), the SKY77643 SkyLiTE™ supports 3G / 4G handsets and operates efficiently in WCDMA, TD-SCDMA, and LTE modes. The module is fully programmable through a Mobile Industry Processor Interface (MIPI®).

The module includes a WCDMA / LTE block for low, high, and mid-bands, a Multi- Function Control (MFC) block, and the RF input/output ports are internally matched to 50  loads to minimize external components. A CMOS integrated circuit utilizes standard MIPI® controls for the internal MFC interface and operation. Extremely low leakage current maximizes handset standby time.

The InGaP die, the silicon die and passive components are mounted on a multi-layer laminate substrate. The assembly is encapsulated in a 4.0 mm x 6.8 mm x 0.8 mm, 42-pad MCM, SMT package which allows for a highly manufacturable, low cost solution.

3G: The SKY77643-21 supports WCDMA, High-Speed Downlink Packet Access (HSDPA), High Speed Uplink Packet Access (HSUPA), High Speed Packet Access (HSPA+), and TD-SCDMA 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 SKY77643-21 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. 3G / 4G Modulation scheme includes:

  • WCDMA Voice Release 99
  • HSDPA categories
  • HSUPA
  • HSPA+
  • TD-SCDMA
  • LTE 1.4, 3, 5, 10, 15, 20 MHz Channel BW
  • TDD-LTE

Features

  • Two T/R (RX) ports and 14 outputs
  • Industry-leading PAE for 3G/4G
  • Optimized for APT DCDC operation
  • Fully programmable Mobile Industry Processor Interface (MIPI) control
  • Dual Low Band RF inputs support separate transceiver outputs or interstage filtering
  • MIPI programmable bias modes optimize best efficiency / linearity trade-off for 3G and 4G; minimizes DG09 for 3G.
  • Small, low profile package: 4.0 x 6.8 x 0.8 mm, Max., 42-pad configuration
