[SOLVED] ads max gain

[hunas2127]

Isn't this how you run a max gain simulation?
From what I’ve seen, the max gain of other transistors had only one turning point.
I’m wondering if this issue is due to the simulation settings.
Typically, the frequency sweep range is set to three times the target frequency. What is the reason for this?
Also, should the K-factor be greater than 1 across the entire frequency range, or only around the target frequency?

Max. gain has two definitions.
Maximum Available Gain where the Stability Factor greater than unity.
Maximum Stable gain where the Stability Factor is smaller than unity.

There isn't any issue in your simulation because if you look at the Stability Factor, it raises greater than unity in a region.
The region between two markers identifies Maximum Available Gain.
