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.

SKY77643-11 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 SKY77643-11 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 SKY77643-11 SkyLiTE™ 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 control of output power. Adjusting the VCC using a DCDC converter maximizes efficiency of each power level and modulation type.

4G: The SKY77643-11 SkyLiTE™ supports 1.4, 3, 5, 10, 15, 20 MHz channel bandwidths. Similar to 3G operation, varying the input power level provides control of output power. Adjusting the VCC using a DCDC converter maximizes efficiency at each power level.

3G / 4G Modulation scheme includes:
  • WCDMA Voice Release 99
  • HSDPA categories
  • HSPA+
  • LTE 1.4, 3, 5, 10, 15, 20 MHz Channel BW


    • Hybrid PA architecture
