800 MHz, 线性dB VGA 内置AGC检测器

AD8368是一款内置模拟线性dB增益控制功能的可变增益放大器(VGA)，可以在低频至800 MHz频率范围内工作。由于采用ADI公司的X-AMP®架构，这种创新技术可实现高性能可变增益控制，因此该器件具有出色的增益范围、一致性和平坦度。\n\n −12 dB至+22 dB增益范围可以按照37.5 dB/V精确调整，一致性误差极小。AD8368的3 dB带宽标称值为800 MHz，其与增益设置无关。在140 MHz、最大增益时，OIP3为33 dBm。输出本底噪声为−143 dBm/Hz，最大增益时的相应噪声系数为9.5 dB。单端输入和输出阻抗标称值为50 Ω。\n\n • 模拟可变增益范围：-12 dB至+22 dB\n\n• 线性dB调整比例：37.5 dB/V\n\n• 3 dB带宽：800 MHz (VGAIN= 0.5 V)\n\n• 集成均方根检测器\n\n• P1dB：16 dBm (140 MHz)\n\n• 输出IP3：33 dBm (140 MHz)\n\n• 最大增益时的噪声系数：9.5 dB (140 MHz)\n\n• 输入和输出阻抗：50 Ω\n\n• 单电源供电：4.5 V至5.5 V\n\n• 符合RoHS标准，24引脚LFCSP封装;
