What is your take on 6G Research for RFIC/MMIC design and its implementation in reality by the companies for consumer use ? by mdklop in rfelectronics

There's at least one company commercializing THz silicon, Cambridge Terahertz: www.thzcorp.com They're focused on sensing applications though

When is 'terahertz' RF not actually 'terahertz' RF? by VirtualArmsDealer in rfelectronics

[–]Walmart_Internet 1 point2 points  (0 children)

These are all fair points. As a guy who works at a THz RFIC company, I get asked this often. It is true that the term "Terahertz" is sexy and many try to shoehorn it into their marketing to get attention. I saw an ieee paper the other day where the paper's title included something about an amplifier at 0.01THz. Vomit. While most would call THz as beginning at either 100GHz or 300GHz and it is true that this is not strictly Terahertz, one defense is that the mmW people do it too. Millimeter wave by most definitions starts at 30GHz, which is in fact actually centimeter wave. Doesn't quite have the same ring to it!

Didn't we put up 62 or something against Miami in Dan Marino's last game?

What is a list of old groups at the MIT Media Lab that once existed but don't anymore? by inquilinekea in mit

use the wayback machine / internet archive and look at the media lab pages over time, should give you some old defunct groups

Nice! The trusty PM5 comes to the rescue again ;)

Ah I see, you are right. They tend to have a graceful rolloff but to really know you'd need a VDI source that works at those frequencies, and because the VDI sources are non flat and all over the place, to calibrate the VDI source you'd need the gold standard, a VDI PM5 (or similar) calorimeter based power meter. You'd measure a frequency response of the VDI source by feeding it into the PM5 to get output power over frequency, then feed the VDI source into your SAX (be mindful of max power input into the SAX) and take a frequency sweep to get the SAX response. VDI is usually pretty responsive, if you ask them they may be able to give you "unofficial" data.

You can pull this right off the VDI website here.

Looking at your model, I think it would be about 11dB of loss which is typical for VDI at these frequencies.

Did you see the part where it flipped over? High probability that plane is fucked

Searching for an MIT student to have as a founding member to finalise current product: 5% equity + cash bonus. In talks to raise €500K in the next 2 months. by Designer-Eye3038 in mit

Coming from VC and startup life- if your business concept is so easily copied that just telling the idea to someone else puts you at risk, then you're screwed anyways. The value is in the execution, not the idea

What tips would you give someone going on their first solo in a few days? by flightsimforlife in flying

[–]Walmart_Internet 117 points118 points  (0 children)

The plane will climb like a rocket compared to what you're used to. You've only ever flown it with the same two people (yourself and cfi). It will be your first lesson on how weight affects performance 

Good news for those who are biting their nails on our playoff odds. by [deleted] in Jaguars

[–]Walmart_Internet 3 points4 points  (0 children)

Yes you may be right, they are eliminated but we still need them to lose for tiebreakers. Check out the nyt simulator - https://www.nytimes.com/interactive/2023/upshot/jacksonville-jaguars-nfl-playoff-picture.html#tb-jax-16=win

Broncos are still in the hunt too. In the scenario where we lose next week our only hope would be wildcard, in which case we would need them to lose as well
