Tool/software:

Hi,

I'm planning to deisgn waveguide antenna.

What I see in your document showed that LoP has been doing sieze reduction
From 4x6 to 4x5 solder balls

In your Encrypt model(4x6 solder balls) has Waveport size :2.18x1.53mm

I have 3 questions:

Q1: What's the WG size of the WG antenna on EVM?

Q2: What's your suggestion about the waveguide size to customer who want to design their own waveguide antenna? WR10 or WR12?

Q3: If I use 2.18x1.53 to design antenna, the cut-off frequency will up to 68.7GHz which is very close to 76-81GHz. Is there any risk?

Hi E. Shareef,

I'd been checking the detail of this checklist. It's all about EE layout guidelinex
I do find the layout guide about the LoP Interface but that's not what im asking for

In the end i couldn't find any of related information about my question.

Could you plesae reply my questions one by one?

Apologies,

I mistakenly thought your questions are for launchers and not the WG.

TI does not design the Waveguides and you will need to get in touch with a 3rd party vendor for more information.

The antenna used on AWR2544LOP EVM is from Golden Devices. They can be contacted here: info@golden-devices.com or directly to email: mark.sippel@golden-devices.com, as well as via Linkedin ==> https://www.linkedin.com/in/mark-sippel-997b7a1b9/?originalSubdomain=de

Hope this helps,
