IMR and active balun
The IMR mixer has two software-selectable FM inputs (referred to as mode 1 and mode 2).
These inputs are implemented with different gains, noise figures, IIP3, maximum input
signal.
There are two single ended outputs of the IMR mixer. One is dedicated to FM (Balunout1)
and the other to AM (Balunout2). It is not recommended to use both outputs in parallel.
