But I have some problems with interfacing AD8332 and AD8333. According to AD8333 datasheet example is AD8332 LNA connected to AD8333. After mixing are I/Q rails connected to transimpendance amplifiers for converting currents to voltage. So, I have single ended signal. But I need to connect this signal back to AD8332 - VGA, which has differential input. Can I simple use an LVDS driver such as ds90c401?
