10MHz distribution amplifier


G4FRE built a 10MHz distribution amplifier:

I have had a need for a distribution amplifier for a while now. Searching around I found the design by G4JNT in Radcom, which filled my needs. I redrew the circuit for 4 outputs and had PCBs made. (if you want one contact me!)  I now have the units in my M1DST 10MHz Thunderbolt monitoring project and in my LPRO101 10MHz Rubidium source.

  1. The LM7171 used in this very simple design can be simulated in LTspice with reasonable results at 10MHz using the non-encrypted PSPICE model from TI (download it from the LM7171 TI homepage and use the LTspice bult-in opamp2.asy symbol). Also look at the LMH6703 part; lower drive current but higher GBW and more. The LMH6703 non-encrypted PSPICE model from TI also works in LTspice but it requires more work to get the symbol to function.
