SKY77606 Multiband/Multimode PAM for Quad-Band GSM / EDGE and Tri-Band (Bands I, V, VIII)

SKYWORKS SKY77606 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, a logic control block for multiple power control levels, and band enable functions in both cellular and UMTS. RF I/O ports internally matched to 50 Ω minimize the number of external components. Extremely low leakage current maximizes handset standby time. GSM/EDGE: The SKY77606 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 SKY77606 uses Switched Load Insensitive Power Amplifier (SLIPA) 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, VIII, and operates at different power modes. The module is fully controllable via three line logic and bandenable interfaces. The InGaP/GaAs die and passive components are mounted on a multi-layer laminate substrate and the assembly encapsulated with plastic overmold. The SKY77606 is a compact, low profile, Surface Mount Technology (SMT) package, which allows for a highly manufacturable, low cost solution.
