I've now run into another problem, as the 4702 employs only one down-conversion stage I'm a little light on gain. As a quick stop-gap measure (I'm still working on designing a second down-conversion stage with associated gain) I'm considering replacing the 390 ohm feedback resistors on the OPA691 with something larger, say 3.9k, to boost things up a bit there. Not being altogether RF savy I thought I'd throw the idea out here before do anything rash.
So, is there going to be any major problem with this strategy? If anyone has other suggestions as to how I should go about getting a little more grunt out of my system, I'd appreciate them as well.

Without looking at anything I note that I2C addresses are 7-bit numbers. The specified address is shifted left one bit then or'ed with 1 for read or 0 for write. Forgive me if I've missed something, or this is already obvious.
