Description
Skyworks SKY77615 is a hybrid multimode multiband (MMMB) Power Amplifier
Module (PAM) that supports 2.5G / 3G handsets, and operates efficiently in GSM,
EGPRS, EDGE, and WCDMA modes. The module is fully programmable through MIPI.
The PAM consists of a GSM850/EGSM900 PA block, a DCS1800/PCS1900 PA block,
a separate WCDMA block for low and high bands, RF input/output ports internally
matched to 50 ohms to reduce the number of external components, and a Multi-
Function Control (MFC) block. A CMOS integrated circuit, using standard MIPI control,
provides 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 6 mm x 8 mm x 0.9 mm,
36-pad MCM, SMT package which allows for a highly manufacturable, low cost
solution.
2.5G:
The SKY77615 supports the GSM850, EGSM900, DCS1800, and PCS1900
bands as well as 2.5G Class 12 Enhanced General Packet Radio Service (EGPRS)
multi-slot operation and EDGE linear modulation.
For both GMSK and EDGE modes, quiescent current is adjusted according to the
output power target using the VBIAS pad in order to minimize current drain at each
power level and output power is controlled by varying input power.
3G:
The SKY77615 supports WCDMA, High-Speed Downlink Packet Access (HSDPA),
and High Speed Uplink Packet Access (HSUPA) modulation. Varying the input power
level provides output power control. VCC is adjusted using a DC/DC converter to
maximize efficiency for each power level and modulation type.
3G Modulation scheme includes:
- WCDMA Voice Release 99
- HSPA+
- HSUPA
- HSDPA categories
