In order to drive an active antenna, I have to set up a jumper at J101
in DBSRX2 board. There is a mark beside J101 which is 3v. I think DBSRX2
change the voltage from 5v to 3.3v. I am not sure 3.3v can drive my 5v
attach antenna or not.
I think the major change of DBSRX2 is using MAX2112 instead of MAX2118
(out of date). Is there any issue if I just replace MAX2118 with MAX2112
and keep the rest same on DBSRX1? That way I can get 5v voltage and low
phase noise.
Thanks
