Awesome. So what if a high current, like a garage door keeps surging back into this isolator, what exactly is the part that wears down? Is it terminal C? I seem to have to keep buying a new isolator for my HFC NBN every year or so, and I don't want to keep doing that, so if I know what breaks, then maybe I can buy a good isolator instead of the same cheap ones.

How much was your financial investment?

You failed to observe and mention that it appears that the "tabbed" portion of copper leading to the resistor is a bit larger (or extends just a bit more) than the other two "tabs" . . .

I've read a different explanation elsewhere. In it, the waves arriving at the two opposite ports are more or less in phase at one port, and out of phase at the second port. Anything to this? If it were merely the hall effect at work deflecting the current, wouldn't these devices need to be biased to ensure that current is always flowing in the same direction through any given port? And of course that is not possible in a three port device, so it would never work.

An Islator and Circulator are basically the same,the difference is the isolator has the third port terminated within the case, the circulator has the third port connected to an external connector for connection of a terminating load. It is really an issue of the needed load wattage; with a circulator the third port can be connected to a 500w dummy load whereas an isolator has only a limited power capacity wit a fixed terminator.

Shame you didn't carry on with these types of video - in many ways you were ahead of the trend. Suspect if you had continued you would have done really well.

Rf isolator

That is actually a circuator. The part in question, is a small 50 Ohm termination. Magnetic rotation causes the R.F to 'circuate' around to the port 2 connection. The load, is for reflected power sent back down the cable, not back into the transmitter. The magnets 'trap' the R.F, and force it to rotate within the field, to the respective ports. Isolators have separate loads and values according to power handling characteristics and frequency range, I.E: 30 to 100 Watt load terminations for potential feedline problems. Isolators are also harmonic generators. Not great, but they do cause IMD products. DO NOT ATTEMPT TO USE THEM IN ANY RECEIVE SYSTEM!

Awesome teardown, visuals and explanation. Thanks!

thank you for the clean, easy explanation

If you swapped the poles of the magnent would you effectively reverse the flow?

Can you do a teardown of fin type RF attenuator?

Just curious could this be the same Zeke of OsmocomBB

only 2 hours?

Super,

Do you have any requirements of RF/Microwave equipment? You are welcome to visit our website www.chbutc.com

hi

Witchcraft. Good video, keep it up. Will sub to see whats coming next.

Thanks for a really easy to understand explanation.

Hi, You know what ferrite and magnets should I use to make a Circulator, where can I buy

If you ever decide to make more videos like this, I feel like it has the potential to become a huge channel.

That was a good explaination, thumbs up!

Great video. :)

Just wanted to know.Can we make a fingerprint scanner on our own ? If so where can I find ..how to ? thanks in advance :)

Awesome dude ! nice work, i searched long time to find a video like this

Outstanding job!

Very nice presentation, please makes more video. I want to understand "Wilkinson power divider" detailed.

Love this! Keep up with these videos, and I love that you keep them quite short aswell. Well done!

Very good! More of these explanational movies. These are perfect!

This is amazing. You should make this the focus of your channel; seeing what's inside gadgets and explaining how they work. You have a knack for teaching and explaining things well.

hi,very nice video dude.is this explanation only for this type of fingerprint scanner?.could you please make one or answer me about the difference of an optical and the ones found in phones.

Can you tear down a bias tee?

I work in RF and I can tell you, you can use them at 300 Mhz as well. Given they are not ASICs.

You are very good. You should upload a new video at least once a week. Next week if i can recommend. DIGITAL CAMERA SENSOR . Just like the finger scanner.

keep it up bro make more videos :)

Good stuff! You want to add some theory with mathematics? Would also love more videos with RF explaining components such as this one. :)

Nice presentation.

Nice, i want to see more, maybe detector mythology, and the mystery of the 'special diodes' and why i they so expensive? Or maybe directional coupler teardowns. Keep it up. You are gifted to explain these things. Cool!

Nice presentation, but why not really explain the theory of operation?
