High Speed and RF Design Considerations

- At very high frequencies, every trace and pin is an RF emitter and receiver. If careful design practices are not followed, the unwanted signals can easily mask those a designer is trying to handle. The design choices begin at the architecture level and extend down to submillimeter placement of traces. There are tried and proven techniques for managing this process. The practical issues of real system design are covered in this session, along with ways to minimize signal degradation in the RF environment.

Wow! That was the most comprehensive RF PCB design and component layout lecture I've ever seen!
Thank you Zoltan Frasch, Senior Applications Engineer, for putting this together. Makes the planning all more important before cutting the schematic.
There is a process and order of that process for sure in RF circuit design and this video helped me learn more of what to add to my already existing process. Thanks!
I'll definitely re-watch this video several times to burn it into my consciousness to include it in my RF circuit design process.
Very insightful! It takes long term experience to realize these otherwise.
Lots of useful and information in here for good PCB design in general. Not just for high speed or RF!
5yr knowledge in 45 min
So Munch info, great tuto, thanks forum sharing, thumbs up.
Glad it was helpful!
Great video. Great content. I've really learnt a lot. Thank you.
Took me forever to find this!!
Excellent presentation!
Best video gem right here.
thank you sir for uploading video....
thanks for making this video .
+Ashish Kushwaha You are very welcome!
I wish I have your knowledge on the PCB design for rf applications!
very usefull, thanks @Analog Devices
You're welcome!
thank you
Gawed Alameri You are welcome!
Hello,
I have a question for you as an expert, what do you say about separating the analog ground area to the digital ground area with a gap, this means that the return currents will not share the same ground plane,
However i had watched a video says that this can cause a differential potential of 1 mvolt between the two ground areas (planes) and hince the external connectors will radiate and hince a failure to meet with EMC requirements?
thanks in advance !
This is old but maybe someone else in the future will reply. From my understanding, no designer in this age will tell you to split the ground planes.. Everyone says you want solid ground plane, just "isolate" (split) the digital and analog sections. I have no idea why they say this, but I've only really seen this split plane idea peddled by datasheets/semiconductor manufacturers in general. Almost a theorist/experimentalist debate. Obviously, they should know their stuff, but I'm wondering if it's just an oldage that may have been fine in the 10s of MHz, but not in the modern era with GHz abundant. But I have very little experience myself to comment for sure.
cool stuff
I am a bit confused, please give me some guidance, sir.
@32:47, X = Copper length (mm) and Y = Copper width (mm),
but @33:25 you say "minimize inductance: increase trace/pad WIDTH"
Now my confusion: For a SOIC the X = 0.51 mm and for a 3x3 mm CSP the X = 0.6 mm (so the length has increased)
So it seems the X (which was labelled as the LENGTH earlier) has increased and the inductance decreased from 0.08 nH to 0.05 nH. So the X would be the width, not the length right?
Please help. Thank you very much for the video.
Does anyone know where can I find the slides? Thanks.
Hello, this was uploaded about 4.5 years ago and the slides are not available. But, we have many articles located on our Analog Dialogue site. Here is a link that searches for "rf design" www.analog.com/en/analog-dialogue/search.html?q=rf%20design
Dat accent! :D
BTW great vid!

There are too many basic things. I feel like at a lecture for Economists or other non-electronics. A more fitting name for this video would be How to make a PCB and some high speed and RF Design...
Dobrý jméno :D

Попытались за 40 минут упомянуть обо всем, в итоге видео вышло вообще ни о чем.... у AD вообще с обучающими видео беда.
