【应用】圣邦微低噪声运算放大器SGM8262-2YS8G/TR应用于AGC电路,速率高,输出电流高达300mA
在射频电路中,用于自动增益控制的电路叫做AGC,主要通过检测输出射频信号功率,并通过运放计算,控制前端的压控衰减器(衰减二极管),自动调整衰减二极管的衰减值,达到稳定的RFout功率。圣邦微推出的低噪声运算放大器SGM8262-2YS8G/TR应用于AGC电路中,能够得到非常优秀的AGC性能表现。
SGM8262-2YS8G/TR应用于AGC电路中的电路框图如下图所示。检波器将射频功率转化为直流电平,通过SGM8262-2YS8G/TR放大,调整其放大倍数,得到适当的电压施加到衰减二极管。输出功率越大,检波电压越高,衰减二极管衰减值越大,降低了链路增益,最终达到控制增益,稳定输出功率的目的。
SGM8262-2YS8G/TR应用于AGC电路中的主要特点如下:
1)速率高:3dB带宽为22MHz,支持高速调制模式的检波。
2)驱动能力强:输出电流高达300mA,能够驱动多级衰减二极管,达到更大的衰减值。
3)低噪声:3.5nV/√100kHz,减少对检波信号附加的噪声基底,检波更准确。
4)耐压高:支持4.5V至36V电压输入,适应电源不稳带来的影响。
5)通用性:该型号有SOIC-8和TDFN-3×3-8BL两种封装,如下图所示,SOIC-8封装更具通用性,可与市面类似物料互换应用,TDFN-3×3-8BL小尺寸封装,适用于对PCB面积比较小的应用场景。
此外,SGM8262-2YS8G/TR是国内知名厂家圣邦微电子推出的,具备国产产品的主要特点,如价格、交期、技术服务、供应保障等优势。在国产化大趋势下,SGM8262-2YS8G/TR是不错的选择。
