三模/双模CDMA LNA/混频器

MAX2323/MAX2325为低噪声放大器(LNA)和混频器IC，为蜂窝和PCS频段的码分多址(CDMA)应用而优化。MAX2323可以为蜂窝FM、蜂窝CDMA和PCS CDMA提供可切换的信号通道，专用于双频、三模CDMA应用。而MAX2325则为蜂窝频段双模器件。\n 为了在最小电流下优化蜂窝频段的动态范围，MAX2323/MAX2325可以实现四种LNA模式：高增益/高线性度、高增益/低线性度、中增益以及低增益。在高增益/高线性模式下，可调节的高截点LNA减小了对强干扰信号的敏感度。其它增益模式下，LNA电流大大减小、有效延长了待机时间。\n CDMA混频器设计成高线性度、低噪声和差分 \n• 2.7V工作电压 \n• 双频三模 \n• 三种LNA增益设置(蜂窝) \n• 二种LNA增益设置(PCS) \n• 低增益模式下18mA \n• 寻呼与中等增益模式下19.5mA \n• 高增益、高线性度模式下26.5mA \n• FM模式、高增益、低线性度模式下16.5mA \n• 串联噪声系数为2.5dB (典型值) \n• LNA IIP3可以在+5dBm至+13dBm范围内调节 \n• 超小型28引脚封装(5mm x 5mm);
