OK, so this probably seems like a fundamental sort of question, but I've
noticed that there seem to be
a couple of different places on the net describing quadrature receiver
toplogies, and I want to know something
fairly simple.
For a direct-conversion quadrature receiver, must you phase split *BOTH*
the RF and LO inputs to the
mixers? That is, do you need a 90 degree hybrid on both the RF and LO
ports?
