Rainbow Photonics AG is who I am thinking of.
@James Finch oh, this looks cool!
W-Band is interesting.
@David Troetschel (Power Factor (loss Tangent) @15°C: 0.0001 - 0.0004) That is pretty good. The issue is more than just the cost of the raw material. Lithography resolution, layers, etc. all have to be taken into account.
Amazed me observing the transition where the circuits turned into optical train like systems designs.
for sure; just an idea
@David Troetschel I'll investigate. Thanks!
A reminder that I'll post a transcript right after the chat, so everyone can refer back to links and such
You can usually split a single sheet into about 20 but I have no idea how crazy you would have to be to try and smoosh em back together after laying traces haha
Any suggestions/requests for videos/ect.?
@The Signal Path I've seen a lot of research in creating digital logic in optical ranges, are you aware of anything being produced in high mm range?
One of the challenges with my channel is that the topics can get fairly advanced, as a result the audience size is always going to be fairly small.
... I really like the sampling osciloscope project from Ted Yapo ... would be nice if you could feature this one in your videos
Yes :) How to re-purpose existing devices to put your hands on microwave stuff while still using RTL-SDR / HackRFOne
that is price baseline for most of folks
@The Signal Path Maybe detailing circuit designs correlating the range of electronic design as well as optical like designs.
@Ethan Waldo Ultra-high speed digital communication is not really digital, it is mixed signal. Wireline links can be made to beyond 100Gbps.
@BSA Secure Ok. I will keep that in mind.
Can you make video about the cheapest chinese microwave test equipmen (spectrum analysets, VNAs)?
@The Signal Path Might even be interesting to demonstrate making a cost effective spectrum analyzer interface into an oscilloscope. Might be a cost effective way to get more out of a scope and maybe in analog ways too first off.
@michal777 It is amazing how much far the Chinese vendors have come in this regards. I will take a look again and see what I can find.
But that almost always uses some specialized transceiver chip as opposed to nuts and bolts digital logic (i.e. NAND)
@michal777 - I agree there must be some good stuff out there for us cheapskates.
@Ethan Waldo Yes, of course. These are not traditional logic gate circuits.
@The Signal Path Would be sweet and totally awesome to be able to detect from the Gamma down to DC... though that's a little excessive of a goal for a smaller package design... though would be interesting to see what the present state of the smallest package can look like.
thank you for the advice, i'll keep it in mind, I don't know if it is possible, but i think it would be interesting an overview or analysis of an IC or IC fabrication, i aIso loved the 24Ghz Doppler radar module, because of the nice analysis of a "simpler" circuit type.
http://www.potatosemi.com/ produces stuff in the 1Ghz max range, and then there's one other that is ridiculously expensive that I can't find right now.
@The Signal Path Seems as soon as the chips come out and there is an evaluation board available... I'm guessing there are Chinese out there trying to engineer the cheapest feasible modules to put on the market...
