Ka-Band (27–31 GHz) Qorvo GaN Models

krycnkaya

Hello,

I am a student and currently conducting a research project focused on the design and simulation of a Ka-band (27–31 GHz) Doherty power amplifier with my universtity supervisors. For this purpose, we filled  the "University Consideration Request" Form from Modelithics website and we have received access to the Qorvo Modelithics GaN Library.

However, we have realized that the models provided in the current library do not cover frequencies above 20 GHz. Since our project specifically targets the Ka-band, we would require nonlinear transistor models that include performance data beyond S-parameters (e.g., IP3, P1dB, gain compression).

I have contacted the Customer Support from Qorvo and they referred me to Avnet. And Avnet referred me here for my questions.

Is there anyone who can guide me on:

1-Gain access to Ka-band Qorvo GaN models suitable for our frequency range, or similar models from a different manufacturer

2-Receive guidance on how to request these models.

We believe having access to these models is crucial for the accuracy of our simulations and for the success of our research project.

Thank you very much for your support and consideration.
(If the question is unrelated for the forum, accept my apologies...)

    Are you sure they didn't mean the Qorvo forums https://forum.qorvo.com/c/rf-solutions/16 ?

    Or they might have meant contacting someone at Farnell/Newark perhaps.

    If the existing models only cover to 20 GHz, then maybe they have not created models they can support beyond that, or it might be restricted (e.g. sensitive or commercially sensitive) information perhaps.

    If they've only tested to 20 GHz then they are unlikely to test more without a business case (i.e. not students). But basically, I do think you need to re-contact the manufacturer, and/or phone Farnell/Newark and try to find the manager dealing with Qorvo products, or be prepared to measure and test yourself.

    Hello again,

    No, they just told me to contact with the local distributors and shared the website link for Avnet.

    I also have been contacting some people for the past couple of days but as you mentioned and as I think, they are restricted and they won't share with a student.

    We are in a tight budget and we wanted to obtain if there was a non-linear model which we could use in AWR MWO/VSS but it seems like we might need to do some changes on the project due to the frequency band.

    Thanks for the help!
