Just a comment that I may have made before. I bought a brand new dual port
GPS HP splitter on ebay about 3 years ago and after a few months it just
died. I had nothing to loose to open it up, so I did. A few quick
measurements indicated that the RF amplifier transistor or FET, was not
getting any voltage at all. I found a small SMD IC that turned out to be a
3.3 volt voltage regulator feeding the front end, and, while it had an input
of 5 volts it had no output. First assuming there was a short someplace I
lifted or pried up the output pin of the regulator and it still had nothing
on it. So, I concluded it was the regulator. I did not have SMD tools at the
time, so, I just used a scalpel and cut the pins off the device and removed
the IC. Then I took a strand from a multi strand piece of wire and
connected/soldered the input trace to the output trace. It has now worked
fine for about 2 years and I expect it to continue. Just wanted to share
this should anyone else experience the same problem. Regards - Mike
