Description

Skyworks SKY77643-81 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 x 6.8 mm x 0.75 mm, 42-pad MCM,

SMT package which allows for a highly manufacturable, low cost

solution.

3G: The SKY77643-81 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 SKY77643-81 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.
