MRF13750H Input Matching Design Simulation

[Luis_V]

Hello!

I am trying to simulate the input matching network of the MRF13750H-915MHz reference circuit board using Usimmics (I don't have ADS neither AWR) 

I am using the same width and length traces as those in NXP datasheet, but the results do not correspond to 915MHz. Does anyone know what I am doing wrong?

Best,

Luis Villanueva

Hello Luis_V

Good day!

Unfortunately, I haven't used the simulator you're using, so I can't make a complete comparison, but from what I can see, I can tell you the following:

In ADS/AWR, the original layout includes:

• tee discontinuities,
• mitered bends,
• open-end effects,
• coupling effects.

Your schematic uses ideal MLIN sections connected directly.

Furthermore, I understand that the AWR simulation "takes into account" the parasitic effects that may be present in the package.

I hope this information has helped you, please let me know if you need help with anything else.

Have a great day and best of luck.

Thank you for the information!
