放大器 低频应用

二者支持100kHz ~10MHz，

如果是RF应用，可以考虑使用RF功放

谢谢您的回答！

RF功放没有能覆盖0.1MHz~10MHz的哦，

您说运放可以覆盖0.1MHz~10MHz，但是测试曲线并没有给出，是否线性度OIP3在低频会恶化比较严重？

产品线的工程师回复如下

The ADA4961 is designed to be AC coupled, and it's gain increases below 10 MHz.  For applications that need flat frequency response near or below 10 MHz, it'll be better to use completely dc-coupled, low-distortion differential amplifiers such as

-- ADL5565  Single-channel, 6 GHz diff ADC driver,

-- ADL5566  Dual channel, 4.5 GHz diff ADC driver, &

-- ADL5567  Dual channel, 4.8 GHz diff ADC driver.
