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
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
- LTE 1.4, 3, 5, 10, 15, 20 MHz Channel BW
