Paul,
Many GPS receivers only use 2,046 MHz bandwidth, but some use the full
20,46 MHz even if they only do C/A. Guessing that you are working on
down-conversion for an old box, then 2,046 MHz will be your answer.
Cheers,
Magnus

I am looking at building a GPS down converter.
LO 1500 Mhz locked to a 10 MHz ref.
The IF will be at 75.42 Mhz how wide should it be?
My question is simple.
What should the IF pass band bandwidth be?
Not sure if it should be 3-4 Mhz, 10 or 15 wide.
Thanks
