描述 Description

Skyworks SKY77601 is a hybrid multimode, multiband PowerAmplifier Module (PAM). The device is intended to support 2.5Gand 3G handsets and operates efficiently in GSM, EGPRS, EDGEWCDMA modes.

For 2.5G, the SKY77601 supports the GSM850, EGSM900,DCS1800, and PCS1900 bands. The device also supports 2.5GClass 12 Enhanced General Packet Radio Service (EGPRS) multislotoperation 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 3GPPincluding bands I, II, V, and VIII.

RF input and output ports are internally matched to 50 Ω toreduce the number of external components. Extremely lowleakage current maximizes handset standby time.

The InGaP die, the silicon die, and passive components aremounted on a multi-layer laminate substrate. The assembly isencapsulated 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 highlymanufacturable low-cost solution.
