供应射频收发器芯片RDA6218+

The RDA6218 is a high-power, high-efficiency dual-band front-end Module. This device is designed for EGSM900, DCS handheld digital cellular equipment. The module consists of dual band power amplifiers and dual band antenna switch. The power amplifiers, switch and their controller are fabricated with GaAs Heterojunction Bipolar Transistor (HBT), GaAs PHEMT and CMOS respectively.The package of this device is 6mm×8mm×1.1mm 20-pins LGA. The input and output are realized on-chip matched to 50Ω. The RDA6218 requires few external components,simplifying PCB layout and reducing PCB boardspace.
