TQP7M9106 S-parameter Modelling Issue

[Rhino]

Hello,
I would like to use TQP7M9106 in my project for 2W, 500-1000 MHz amplifier.

Firstly I checked datasheet schematic (TQP7M9106-PCB900) for 920-960 MHz and have a issues with results.

We think s-parameter file for TQP7M9106 is not correct. We check using both uSimmics 5.8 (with ideal components) and AWR Design Environment V15. (with s-parameters components)
TQP7M9106 S-parameters from TQP7M9106 - Qorvo

Result below.

1. uSimmics
   

   
   
   
   
   
   
   

2. AWR Design Environment V15
   

   
   
   
   
   
   
   

Both modelling results are very similar and not expected.
Probably TQP7M9106-PCB900 schematic\BOM is not correct or TQP7M9106 s-parameters is not correct.

I would be gratefull for any comments, ideas and recommendation.

– Kind Regars,
Victor

Hi,
The TQP7M9106 datasheet provides a list of critical component placement locations for this tune on page 4:

• Center of C8 to TQP7M9106 (U1) device package is 243 mil (11.7º at 940MHz)
• Center of L5 to TQP7M9106 (U1) device package is 452 mil (21.8º at 940MHz)
• Center of C9 to TQP7M9106 (U1) device package is 275 mil (13.3º at 940MHz)
• Center of C2 to TQP7M9106 (U1) device package is 355 mil (17.2º at 940MHz)
  These should be included in your simulations. There is a reference design for 450-800MHz, see attached.

Hello,
Thank you, MJT.

Are there other TQP7M9106 Ref. Designs or Application Notes not listed on the product page?

[MJT]

Other available designs are 700-1000MHz, 700-800MHz and 700-900MHz

[Rhino]

Where can I find them? Is there a link?
