Analog Devices / Maxim Integrated SC2200 双通道射频功率放大器线性化电路
Maxim SC2200 双通道射频功率放大器线性化电路是一款射频功率放大器线性化电路 (RFPAL)，与上代产品相比，提高了集成度和功能性。 此器件为双通路线性化电路，是完全自适应、RFIN/RFOUT 预失真线性化解决方案，专门针广泛系列放大器、功率调节和通信协议进行了优化。 它支持 2G 至 4G 标准 (FDD 和 TDD)，覆盖 698MHz 至2700MHz 范围，以及 60MHz 到低至 1.2MHz 的扩展信号带宽范围。 SC2200 支持单端 RF 信号，无需非平衡变压器，具有镜像引脚排列，便于两个通路的设计。 此双通路线性化电路可用于小蜂窝 MIMO、有源天线、分布式天线，或要求两个不同单频段的系统。
The Analog Devices SC2200 Dual RF Power Amplifier Linearizer is available in an 11mm x 11mm SAWN QFN package.
