Dear Analog Devices,
We are currently looking for one component which can convert four differential I and Q signals to single ended I and Q baseband signals (4-to-2), and one component for the inverse way (2-to-4). The bandwidth of baseband signals is 150MHz. We are not familiar with the concept "common mode voltage", however based on our device working environment, it seems that DC is not required to be considered. Any comments are very welcome.
