功能特点
GSM Power Amplifier Module
The RDA6255 is a high-power, high-efficiency tri-band power amplifier Module. This device is designed for EGSM900, DCS, and PCS handheld digital cellular equipment. The power amplifiers and their controller are fabricated with GaAs Heterojunction Bipolar Transistor (HBT) and CMOS respectively. The package of this device is 5mm×5mm×1.1mm 16-pins LGA. The input and output are realized on-chip matched to 50Ω. The low-pass filter for ramping signal is integrated in CMOS controller. The RDA6255 requires few external components, simplifying PCB layout and reducing PCB board space.
