General Description

The RDA6861 is a high-power, high-efficiency multiband multimode front-end Module. This device is designed for quad-band GSM/EDGE (GSM850, GSM900,DCS1800,PCS1900) and WCDMA/CDMA/LTE handheld digital cellular equipment. The module consists of multiband multimode power amplifiers and multi-throw antenna switch. The power amplifiers, switch and their controller are fabricated with GaAs HBT and CMOS respectively. The device package is 6mm×6mm×1.1mm 40-pins LGA. The input and output are realized on-chip matched to 50Ω. The RDA6861 requires few external components, simplifying PCB layout and reducing PCB board space.
