Description

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

solution.

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

level.

3G/4G modulation scheme includes:

• WCDMA Voice Release 99

• HSDPA categories

• HSUPA

• HSPA+

• CDMA2000 1xRC1, 1xRC3

• CDMA2000 EVDO

• FDD LTE

• TDD LTE

• Uplink Carrier Aggregation (CA) support for

Bands 1, 2/25, and 3 (up to 40 MHz)
