Tx-Rx iPAC™ FEM Dual-Band GSM/GPRS GSM850, PCS1900

SKY77517 is a Tx-Rx FEM with iPAC™ for dual-band cellular handsets comprising GSM850 and PCS1900 operation and supports Class 12 GPRS multi-slot operation. The module consists of two HBT PA blocks—for GSM850 and PCS1900 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.
