Unknown Impedance
Hi,
I have the new GPS down convertor IC from Maxim, and unfortunately the true differential output impedances of mixer outputs and input impedances of mixer outputs are not known. Maxim tried to help on this but they require more time for the correct answer. The IF2 output is at 15.42MHz. I need a bandwidth of +/-8MHz. Should I use the approximate impedance provided by Maxim and design a passive filter or use an active filter with larger input impedance and lower output imp.
TIA
PS: I am beggining to like these forums
