When HB simulation is performed, the output power corresponding to the 1dB compression point cannot reach 46dBm. What is the problem? The output power of the transmission curve is only 28, which is the trans graph.

I'm free. Let's see what time it is to go to work.

ManU7 posted on 2021-11-4 22:48 The matching one here is 46db, that is, during HB simulation, the output power RF Power of the transmission curve is only 28, what should I do?

Here is one, take a look first

Could you please send me a simulation?

What simulation, harmonic simulation?

This material is also learned from Teacher Xu's textbook, and then verified by myself. Only by experiencing the knowledge points in the book once by myself, on the one hand, it is verification, on the other hand, it is consolidation, and on the other hand, it is a breakthrough. We do not advocate the spirit of learning by analogy. The teacher has published a book, so we learn according to the method and put it into practice.

LZ's explanation is very good, let's learn from it

Is LZ still here? My HB simulation also reports an error and no result. I don’t know why.

This is my file. Before HB simulation, the results are the same as in the book. But HB simulation cannot be done. I don't know why.

What do you mean it hasn't been installed yet? Is it because the software is not set up correctly?

Is this a compressed project file? Packaged? Do I need to see it?

You don't deal with a bunch of warnings, but warnings don't affect your results.

It is a project file. I compressed it. I wonder if you can help me take a look. I really can't figure it out. I followed Mr. Xu's book. There was no problem in the front part. But after the HB simulation, all the warnings appeared and no results were output.

I made it. When I simulated the inductor short circuit, the button was always pressed and it failed. I was wondering why there was no result.

In addition, I also found that in the BIAS bias circuit, DC_BLOCK must be disabled or replaced with a 1μf capacitor in order to successfully perform S parameter simulation and HB simulation. This is not mentioned in the book, and there are different opinions on the Internet. I don’t know what the principle is

Carefully check the parameter settings, basically it can be done
