Correct. For those (who don¹tt already know) that are interested in
learning about this, do some reading on Diplex Filters
(http://en.wikipedia.org/wiki/Diplexer), which are used to ³split² the RF
spectrum apart so that the lower portion and the higher portion can be
amplified independently, before recombining the two portions. I believe
this was done to accomplish unity gain in each direction independently.
Also, I¹d like to note that there have been a few comments in this thread
that lead me to believe some folks are confusing asymmetrical routing
paths with asymmetrical speeds. Don¹t confuse the two as they have nearly
nothing to do with one another.
