SKY77340

Power Amplifier Module Quad-Band GSM/EDGE GSM850, GSM900, DCS1800, PCS1900


Please note: this product is being discontinued and is not recommended for new designs.

SKY77340 PAM is designed in a compact form factor for quad-band cellular handsets comprising GSM850/900, DCS1800, PCS1900, supporting GMSK and linear EDGE modulation, and Class 12 GPRS multi-slot operation. Two separate HBT PA blocks supporting the GSM850/900 band and the DCS1800/PCS1900 band are fabricated onto InGaP die. Inputs and outputs are impedance-matched to 50 ohms, and a custom CMOS IC provides the internal MFC function and interface circuitry. The InGaP die, the silicon die, and the passive components are mounted on a multi-layer laminate substrate and the assembly is encapsulated with plastic overmold.
