The RDA6585 is a high-power, high-efficiency multi-mode front-end Module. This device is designed for quad-band GSM/EDGE (GSM850, EGSM900, DCS1800, PCS1900) and TD-SCDMA handheld digital cellular equipment. The module consists of multi-mode multi-band 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 28-pins LGA. The input and output are realized on-chip matched to 50Ω. The RDA6585 requires few external components, simplifying PCB layout and reducing PCB board space.
