Hi, I have found this preamplifier which can work on 7MHz and has a relatively high dynamic range
https://www.sv1afn.com/2n5109.html
I would like to replace the one I use on my circuit (attached) with this one, or another one that has a higher dynamic range than my circuit, so that I can reject some of the IMD currently noticed with the current amp.
I do not want push pull or transformers, and I try to avoid inductors for this simple design.
I wonder, how much gain will my simple preamp (attached) have?
Also, can I somehow transform the 2n5109 circuit to use an inductor/capacitor at the drain and no transformer?
Finally can I remove the base inductor?
I do not stick on this circuit, any other simple circuit will be appreciated
Thanks and have a happy 2017!
