Awesome video. Still hoping you will do a video on Atomera's MST technology. I think it will be the biggest thing to happen this decade for boosting semiconductor performance.

I find fiber optic to be faster. I do not use wireless at all. I use ethernet for my internet. I avoid wireless as much as I can.

Josh? (21:12)

I don't know who I am

I been saying the same. Go ATOMERA!!!​@excitedbox5705

I’d like to but I also want to stay sane.

@@Asianometry take a shot at it - would be great content.

Flat foil antennas - also a work of art. They fiddle with parasitic and transients to cover multiple frequencies, e. g. 900/1800 and ..850 or 1900!? Then they add a flat hooked L to the foil pattern shape for... Something else. There are patents and I imagine a lot of inside art.

Almost witch craft . But then you see them tuning them sometimes with a scalpel by just cutting them

RF information is so difficult to find, especially highly detailed videos or websites that dig into formulas and practical examples. Making any frequency above 200 MHz and amplifying the signal seems to be impossible for me. Another hard piece of information to find is anything about radars that goes into detail.

We've become a nation of users - where the average person has no idea what went into the things like their phone that they use.

People are very good at taking everything for granted

​@@jackthompson6296 true but its part of the progress and movement to simply get 'bored' of the already archived status quo

That's engineering for you. When you do a good job, nobody notices. Just the nature of the beast.

@@Zadster You get (if you are lucky) a few golf claps out of program management - but that's it.

How about PAWG resonators haha

Remember when every video had swooshing sounds every time a slide changed?

Yeah I laughed out loud at that. Based on that price, enough SAW to cover an entire generation of iPhone wouldn’t net enough profit to cover a single photomask.

I think most of the viewers should be clever enough to figure out that little aprils fool joke by themselves.

In the video's defense, it says that you can fill the bucket with RF filters for MORE than what the bucket costs

all I got from this was Short RF Semiconductor stock. say less king 😂😂😂

What company is GTE?

digital.library.mcgill.ca/images/hrcorpreports/pdfs/6/637286.pdf

The Panavia (European) Tornado aircraft's GMR (Ground Mapping) RADAR used a SAW filter for pulse compression and de-compression in the LRU 4 receiver module IIRC ... a swept RF signal was sent in, and a longer, stretched signal spread in time came out, and vice versa on receive.

Your father must be proud of you keeping his stories alive.

Funny, too, how many people think that apple "invented" the "smartphone", when Nokia was doing web browsers and email for. *YEARS BEFORE APPLE!* In fact, most of the technology in use today, originally existed inside Nokia... Was there, developed some of it

re: "a 40-band phone may not have 40 filters" Yeah, many of the bands are adjacent, so, one filter covers multiple so-called 'bands' ... this is getting into the weeds though now.

Baseband scalable filtering applied. As well 40 bands sometimes logical terms since different technologies use same frequency allocation, but have different number assignments.

@@eugen19 One observation that was made, maybe 10 or 15 yrs back on an iPhone, we found that a 2 Watt or so UHF radio in transmit within a couple feet would force the iPhone to 'lose the call' (drop) in progress ... we theorized the strong UHF signal perhaps overloaded the wideband front and even with 'filtering' before it, so filtering is never absolute in function, its a relative thing, with the skirts still allowing some signal ingress into the phone.

A modern multimode antenna design is actually a specially selected magical sigil corresponding to the most appropriate demon for the application; electrical signals activate the sigil, calling forth a tiny demon inside the phone, radio, or somesuch communication equipment. The demon is handed a very small letter containing one or more data packets. The demon then steps over to the recipient equipment sigil instantaneously. After the demon takes a short cigarette break to impart the appearance of a lightspeed propagation delay (these breaks are a condition in their employment/capture contract, and if these break times are withheld in the name of improved corporate efficiency, say, or maybe in a shortsighted effort to create a superluminal network, the demons get angry and go on strike and start bashing about breaking all the fragile things we tend to enjoy, like airplanes and time and global causality.) At the appropriate time, the demon places the letter upon the receiving sigil, whereupon the letter disintegrates into a quite beautiful puff of brightly colored particles with an astonishingly short half-life - so short, in fact, that they nearly always expire an infinitesimally short time earlier than they are created. Sadly, though known to be of exquisite beauty, this means they are invisible, thoroughly undetectable by any means, ever, and have never been witnessed. Despite this author's allocation of a significant portion of this paragraph to their detailed description, these particles are completely irrelevant to the sigil based communication system, of course. Under the cover of this completely invisible and useless smokescreen, the demon deftly extracts the letter contents before it vaporizes, hides it up his sleeve, and then slowly backs up in a very suspicious and conspicuous manner toward the baseband processor, and, once he believes nobody is looking, opens it up, shakes out a jumbled collection of 1 and 0 binary bits from his sleeve, closes the processor, and sneaks away. Thus are delivered the contents of the data packets to the recipient device. Of course, though all the bits are accounted for typically, owing to the incompetent data integrity measures inherent in a demon's shirt sleeve, the bits are in random order and better approximate a digital sampling of thermal noise than the desired message. As they are utter bunk now, the baseband processor simply deletes the received bits and replaces them with a perfect, in-order copy of the original message, using magic.

@@user-li4zs1bc7c Um, well, not even close, but, you do you - 'k?

@@user-li4zs1bc7c Best description ever :)

​@@user-li4zs1bc7cI knew it!

@@user-li4zs1bc7c 😂

And also every car and garage door remote control had a saw oscillator to get the size down.

@@Penfold42I think that was also about getting good stability cheaply - early keyfobs had nasty LC oscillators tuned by bending turns of a coil ( PLL synths were too costly and power hungry)

@@mikeselectricstuff so true. And often detuned by the person holding them !

wow, I though those things were solid state, but they're part mechanical, amazing.

The Zenith "M1" module comes to mind. We were using those in Dallas to decode subscription TV channels with an add-on digital board that did sync restoration and video inversion, as I mentioned, this was a subscription (pay) service.

I'll wait for that one comment with proper math, including fill-in ratio for 3 dimensional bucket

Yea, kinda suprised Asianometry dident noticed this himself when he read the script Scriptwriter clearly fucked up. Someone read $1.40 to $1.60 and went 'ohh, thats cheaper than a bucket'..

Yeah that was either bad writing or a misunderstanding. He was describing bulk pricing but misinterpreted it as an insanely low unit cost.

Yeah, even I was caught off guard by that

None of you thought about it for even two seconds, he said MORE than what the bucket costs. It's a joke. It flew like a Concorde above your heads. If the bucket costs $4, and filling it with filters costs $4,000,000,000, it costs MORE to fill the bucket than what the bucket costs. He did not say LESS. T_T

Same thing is happening in Australia, farmers are not happy because of coverage issues.

We're not alone. This shirt-pocket Sony Ericsson goes back 15 years. It'll be like throwing out a favourite smoking-jacket.

Bring on n71

I think this rectifies itself once they start using the old 2g frequencies for 5g.

He says"each filter can be bought for $1.40 to $1.80 when bought in volumes of 50 million" so I think he has it right, but then I don't understand the statement about the bucket.

@@snorman1911 yeah and as someone else pointed out he says “more than what the bucket costs” then said he felt bad for the manufacturer’s profit margins. It’s just a dumpster fire series of sentences. lol

That is seventy million dollars not one dollar and fifty cents for fifty million units?

@snorman1911 It's not your average bucket. 😁

@@Grak70 it was a joke

I wore headphones and felt him in my soul

Definitively not a piezo-electric or mems-microphone. Microphones is a fun topic, though. You can do insane things with arrays of mems-microphones, but for reproduction of the human voice or musical instruments, a cluster of designs from about 90 years ago, the capacitor, the moving coil and the ribbon element microphone transducers are still prefered.

I spent a stint at DSC/Alcatel supporting the Japanese PHS (Personal HandiPhone System) VMC (Voice Mail Center) back in the 2000 timeframe ... I did maintenance programming on the code that interfaced with the ISDN PRI cards, the PCs that held the PRI cards ran scripts to prompt the caller for info, announce messages and so forth ...

DC to daylight indeed. Imagine if you could see all the wireless waves 😮

That's a cool idea.

Correct

No, the loss is the unavoidable side effect. Applying a signal outside the resonator frequency just doesn't generate these waves so they don't make it to the other end.

Put "selectively" in front of transform. Change "audio" to "mechanical"? Delete the loss sentence. Loss here means look somewhere else for perpetual motion machine :) In this case mechanical is adiabatic acoustic energy propagation via a surface mode wave. (Acoustic does not mandate audio. Aka all dolphins are whales, not all whales are dolphins)

What did you guys at TriQuint do with the Dallas Tx division that was doing GaAs MMICs? I worked in the group on the 90's.

small correction though, UMTS(3G) was already (mostly) IP-based, only voice was still circuit-switched

And, referring to the note in the description, that's not how the geographical location "RAH-lee" is pronounced either.

Also "aluminium" from an American :D

That would be an interesting topic. LIDAR investment has rocketed in recent years to target the automotive industry. I think it's tool soon to see who wins, but the story of Velodyne used on the first Darpa Grand Challenge through to some of the solid-state LIDARs availiable now would be really interesting. Tesla of course famously has shunned LIDAR and gone all in on cameras. Some of the spinout technology has gone back into the traditional LIDAR markets.
