Optimization Error while designing Power Amplifier using ADS

[pusparaga]

I have designed Power Amplifier(PA) using ADS2022. I am getting error while optimizing PA. I didn't know where I am making mistake.

You always use "optimization" feature blindly then you ask "where I'm wrong ??"
Before optimizing a system ( any type PA, LNA or others ) you have to have essential knowledge about that system. If you don't do that, you get so weird results like TL13 ( W=890mm L=14mm )

Have you ever seen a Transmission Line with 89cm width, 0.14cm Length ?? You make it short circuit then looking for the error???
Change your mind dear friend. A design engineer must apply "the essentials" then optimize.

Yes I did mistake. I wanted to type for TL13 W = 890 um instead of 890 mm and L = 14 mm.
After correcting also these, I am getting error.

As you said. It is correct. I wanted to type L = 890 um instead of 890 mm and L = 14.3626 mm. But still it is showing error.

The ADS message that you show tells you exactly what the error is, and how to fix this.

Every seems to be ok. Still I am getting error.

When I do optimization for S11 and S22, I am getting results nicely without any optimization error. I have attached same results below.
But when I include Pdel_dBm, LS_Gain_dB and dBm(Vout) these for optimization. I included correct measurement equations also. I am getting optimization error.
