Skyworks SKY77638-51 SkyLiTE™ is a multimode multiband
(MMMB) Power Amplifier Module (PAM) that supports 3G/4G
devices and operates efficiently in CDMA, WCDMA, 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 and mid-bands,
and a Multi-Function Control (MFC) block, RF input/output ports
internally matched to 50 Ω to reduce the number of external
components. A CMOS integrated circuit uses standard MIPI
controls to provide the internal MFC interface and operation.
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 x 6.8 mm x 0.71 mm, 42-pad MCM,
SMT package which is a more highly manufacturable, low cost
3G: The SKY77638-51 supports CDMA, WCDMA, High-Speed
Downlink Packet Access (HSDPA), High Speed Uplink Packet
Access (HSUPA), and High-Speed Packet Access (HSPA+)
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 SKY77638-51 supports 1.4, 3, 5, 10, 15, 20, 30, 35, and
40 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
