SKY77601 Multi-Mode, Multi-Band Power Amplifier Module for Next Generation GGE and HSPA Handsets

SKYWORKS SKY77601 is a hybrid multi-mode, multi-band Power Amplifier Module (PAM). The device is intended to support 2.5G and 3G handsets and operates efficiently in GSM, EGPRS, EDGE WCDMA modes. For 2.5G, the SKY77601 supports the GSM850, EGSM900, DCS1800, and PCS1900 bands. The device also supports 2.5G Class 12 Enhanced General Packet Radio Service (EGPRS) multislot operation and EDGE linear modulation. For 3G, the PAM uses Load Insensitive Power Amplifier (LIPA®) circuitry to support WCDMA, High-Speed Downlink Packet Access (HSDPA), and High-Speed Uplink Packet Access (HSUPA) modulation at a high antenna Voltage Standing-Wave Ratio (VSWR). This functionality covers multiple bands for 3GPP including bands I, II, V, and VIII. RF input and output ports are internally matched to 50 Ω to reduce the number of external components. Extremely low leakage current maximizes handset standby time. The InGaP die, the silicon die, and passive components are mounted on a multi-layer laminate substrate. The assembly is encapsulated with plastic overmold. The device is mounted in a 34-pin, 6 x 8 mm MCM Surface- Mounted Technology (SMT) package, which allows for a highly manufacturable low-cost solution. A block diagram of the SKY77601 is shown in Figure 1. The device package and pinout for the 34-pin MCM are shown in Figure 2.
