CATV上行放大器

MAX3507是应用在CATV上行发送器中的可变增益功率放大器。可变增益具有55dB的动态范围，经由3线SPI™接口进行控制。当使用+34dBmV额定输入信号驱动时，该器件可以输出+64dBmV (16QAM/QPSK)。截止频率为75MHz的片上抗混叠低通滤波器节省了系统设计的成本和空间。可选的正向斜坡发生器使系统设计具有灵活性。\n 该器件采用+5V单电源供电，在最大增益(100%占空比)下发送时吸取220mA额定电流。对于突发模式应用，两次突发之间器件被关闭，以便降低噪声并节省功率，同时，仍然保持输出匹配。该器件被优化为高线性，谐波电平低于-55dBc。\n MAX3507采用2 \n• 内置5阶椭圆抗混叠滤波器 \n• 工作频率5MHz至65MHz \n• 55dB增益控制范围 \n• 可选的正向斜坡发生器 \n• 发送波段具有55dB的无杂散动态范围;
