求一款高频（10MHz以上）可调增益放大器，用来放大微弱的10MHz的正弦信号？请TI的技术人员可以推荐一款
放大微弱的10MHz的正弦信号, 不知道是多微弱. 建议根据其他参数在官网选个高速运放 http://www.ti.com.cn/lsds/ti_zh/analog/amplifiersandlinears/amplifiersandlinears.page
可编程增益的PGA系列放大器没有可以满足10M以上的，建议采用其他方案
不过TI有可变增益的高频运放如LMH6518 900 MHz, Digitally Controlled, Variable Gain Amplifier
LMH6518 900 MHz, Digitally Controlled, Variable Gain Amplifier
VCA820 150MHz SMALL-SIGNAL BANDWIDTH
等等
