Nice project Greg, I'll keep an eye on it. I would like to start with RF designs, but its pretty expensive the gear and hard to find good second hand ones here in Brazil.. you know the thrill.
Hello Gregory, I love your channel and your way of explaining microwaves, I am a radio amateur and I am starting out in the exciting world of microwaves. I am interested in your digital wattmeter, where I can get the information to set up one for my shack. Thank you so much
@@AllElectronicsChannel Joking aside, was wondering at what point do you need to use classified semiconductor technology to generate it. It must be in the 300 GHz range for sure. I wanted to see if you could make 95 GHz because that is used to heat the outer layer of the skin in this microwave anti personal device. I suppose using a frequency doubler or tripler is in the cards because you can probably find a VCO that puts out 30-33 GHz. Problem is that circuit will have to proactively be built on top of itself in a 3d-like manner. Regular coax isn’t going to work either.
What did the prescalers do to you? Did they steal the girl you like or something? Just kidding, great content as always, I'm really looking forward to it, especially the sampler seems like a very intersting part to design. I find the 10GHz range to be pretty hard to prototype, since 1mm of error in a dimension is quite significant already. Also the dielectric losses of FR4 get pretty high pretty quick. You can get pretty good parts and boards by tearing apart LNBs, especially the older ones, since they operate at roughly the frequency you want. Greetings, Michael
Hahahahaha prescalers are the easy way!! Yep.. I don't know if 10gig will work on FR4.. But the BPF transistor has a lot of gain I'm seeing packs of 15 LNBs new very cheap.. is it worth to buy for parts? It's like $2 USD each
@@AllElectronicsChannel I don't think a pack of 15 LNBs is really necessary but one or two to take a look at are pretty nice in my opinion. But keep in mind that the modern types are not as interesting as the older ones.
awesome project. totally with you on not using pre-scaler, that's for cheaters ;-) (i'm kidding of course) using sampler is how 'real' designers got around with this. you can see a similar thing in many high end spectrum analyzers. looking forward to see next video
@@AllElectronicsChannel yeah, I understand. I am italian and also, when I speak english while doing/thinking complex stuff, I experience a drop in english-skills :P
Excellently presented video and a totally interesting project. I'm a newly licensed amateur and a bit hooked on the GHz bands, so hoping to follow along for some short range home-brew transmissions. Also a masterclass in jump cut editing ;)

BROTHER I AM FROM INDIA AND I LOVE YOUR VLOG , THANK YOU FOR SHARING KNOWLEDGE WITH US.

Thanks!
WoW I had never seen that design of PLL very nice
Go go go !!!
Regarding the need to down-tune the quartz a bit - would it have helped if you started the design with a 33 MHz oscillator instead?
Tell me more..

excellent design, hope it works
Fingers 🤞!!
What are some good books for 100 GHz?
Also wanna know!

Ebay probably have a lot o Russian parts...

the problem is you cant even read it with your oscilloscope so how do u know its even there.
Spectrum analyzer !
Awesome stuff!
Thanks man!!

Thanks!! Let's go by the harder way hahaha
1:10, You don't know how to pronounce 5th = fifth ? Ahahah I laughed :)
Great video as usual!
Hahahahaha, English is not my first language! Thanks!!

Hahahaha thanks!!
I need a mobile network repeater circuit, circuit 900mhz 1800mhz 2100mhz🙏
😱😱
Eagerly waiting for videos on RF filters at S and X band 😅
😝😝
It's use airport airline only army secretary used
Fifth Harmonic
And how is the 50 th ?? I pronounced it wrong so.. just listened it with Google translate haha
@@AllElectronicsChannel it is written as Fiftieth and pronounced ˈfiftēəTH
@@AllElectronicsChannel look forward seeing the video... Obregado
