Description
Skyworks SKY77605 is a hybrid multimode, multiband Power
Amplifier Module (PAM) that supports 2.5G and 3G handsets, and
operates efficiently in GSM, EGPRS, EDGE and WCDMA modes.
The PAM consists of a GSM800/EGSM900 PA block, a
DCS1800/PCS1900 PA block, separate blocks for WCDMA
operating in low / high bands, RF I/O ports internally matched to
50 Ω to reduce the number of external components, a logic
control block for multiple power control levels and band enable
functions in both cellular and UMTS. Extremely low leakage
current maximizes handset standby time.
GSM/EDGE: The SKY77605 uses a new compact architecture to
support GSM850, EGSM900, DCS1800 and PCS1900 bands. The
PAM also supports 2.5G Class 12 Enhanced General Packet Radio
Service (EGPRS) multi-slot operation and EDGE linear modulation.
WCDMA: The SKY77605 uses Load Insensitive Power Amplifier
(LIPA) circuitry to support WCDMA, High-Speed Downlink Packet
Access (HSDPA), and High-Speed Uplink Packet Access (HSUPA)
modulations at moderate antenna Voltage Standing-Wave Ratio
(VSWR). This functionality covers multiple bands for 3GPP,
including bands I, II, V, VIII, and operates at different power
modes.
The module is fully controllable via three line logic and band
enable interfaces. The InGaP/GaAs die and passive components
are mounted on a multi-layer laminate substrate and the
assembly encapsulated with plastic overmold. The SKY77605
Surface-Mounted Technology (SMT) package offers for a highly
manufacturable, low-cost solution.
Figure 1 shows a functional block diagram and Figure 2 shows
the pad locations.
