芯片型号:RDA6577

功能特点

RDA6577 is a high-power, high-efficiency front-end Module. This device is designed for GSM /EDGE/ TD-SCDMA /WCDMA handheld digital cellular equipment. The module consists of GSM/EDGE /TD-SCDMA multi-mode PA and SP7T antenna switch. The switch in RDA6577 has three throws for external UMTS ports. The power amplifiers, switch and their controller are fabricated with GaAs HBT and CMOS respectively.

The device package is 5mm×5mm×1.0mm 32-pins LGA. The input and output are realized on-chip matched to 50Ω. The RDA6577 requires few external components, simplifying PCB layout and reducing PCB board space.
