real NF

[mrdummy]

I used the NF palette to calculate the impedance for low noise.


I assumed that by setting Z0 and Zi, I would achieve the best noise figure.


However, as you can see, there are some differences between them.
Is my design correct?
Is there any way to make NF2 match NFmin?
And can I achieve a better noise figure once I complete the design?
tt and yy are from palette and uu ii are from my design
i think i can not reach better than 6 nf in 6 ghz right?

There is a sign error.
Z_OPT(NF)=7.11-j*21.4 Ohm but you assigned +j*21.4

as you know zi should be conjugate
however i did that and that was completely wrong

Not conjugate of the source impedance. It will be exact impedance of the source that you have found.

and as i mentioned before i didnt conj but the result was worse than before.
