MRF8P9040N Verification Simulation

1. Overview of all project files

Second, do a static bias scan of the tube, build the circuit, insert the template, and set the S parameters as shown below:

Static operating point data output by simulation

3. Do LOAD-PULL

Fourth, Sourcepull has templates, just load it in ADS

5. Perform output out simulation (simulation from the tube port to the load)

Smith simulation matching circuit

S parameters Internal sub-circuit microstrip distributed parameters Original device values

Output S11 parameter value as shown below:

Actual component values replaced [out subcircuit]

Output subcircuit packaging model

6. inmatch matching (in subcircuit)

S parameters Internal sub-circuit microstrip distributed parameters Original device values

Input subcircuit (S parameter design matching)

Input subcircuit actual replacement of ideal components

Display file symbol under the main file

7. Bias circuit design

Bias circuit package file

8. HB Harmonic Balance Simulation

IX. Sub-circuit joint simulation

10. Layout simulation

SCH generated layout

11. After the overall subcircuit simulation, a step was missed: stable simulation [K>1]

12. ADS conversion and export

This error occurs in the first simulation step. How can I solve it?

There is a problem with your model. There is a missing file.

I can only download the 2020 version of designkit on the official website, but ADS is 2021. What should I do?

It should be simulatable. Mine is also

HB simulation reports so many errors, what is the problem?

The short circuit problem has been solved. The T pin cannot be grounded. However, the unphysical lines still exist. Which parameter is the problem? I strictly follow the book.

This is the compressed file.

I would like to ask, when HB simulation is performed, the output power corresponding to the 1dB compression point cannot reach 46dBm. What is the problem? The output I achieved is around 28.

You have to adjust the input and output, input power, etc.

The matching here is 46db, which means that during HB simulation, the output power RF Power of the transmission curve is only 28. What should I do?
