SKY77518
Tx-Rx iPAC FEM Dual-Band GSM/GPRS GSM900, DCS1800

SKY77518 is a transmit and receive FEM with iPAC™ for dual-band cellular handsets comprising GSM900 and DCS1900 operation and supports Class 12 GPRS multi-slot operation. The module consists of two HBT PA blocks—for GSM900 and DCS1900 bands—fabricated onto a single Gallium Arsenide (GaAs) die, 50-Ohm impedance-matched inputs and outputs, Tx harmonics filtering, high linearity and low insertion loss PHEMT RF switches, diplexer and a PAC block with internal current-sense resistor. A custom BiCMOS IC provides internal PAC. The GaAs die, PHEMT die, Si die and passive components are mounted on a multi-layer laminate substrate encapsulated with plastic overmold.

SKY77518-11A and SKY77518-21 have been discontinued and are not recommended for new design
