LNA Amplifier gain

(1/2) > >>

ko4nrbs:
If using one of these with a Frequency Counter with a pickup coil how much gain would be needed?  Unfortunately, the gain is not adjustable of these.

_Wim_:
You can put multiple of these in series if gain is not enough. What are you trying to achieve exactly?

Just want to be able to use a pickup coil on my Frequency Counter to read the frequency of the VFO externally.

TimFox:
Do you have any estimate of how much voltage you will get from your search coil in this application?
(I am sure none of us can estimate that for you.)
If not, try one of these amplifiers and see how much you get from it to continue your design.

ko4nrbs:
I may buy a few of them and test to see how much gain I will need.
Thanks,
Bill
